How do i display linux command result in html [duplicate]

This question already has an answer here:
Formatting issues when unix file is sent to mail
(1 answer)
Closed 1 year ago.
I want to run linux command(ps aux --sort -rss | head -n 10) and display the result in table format in mail.
can somebody please suggest.
here is my script.
#!/usr/bin/ksh
current_dir=$(pwd)
script_dir=$(dirname $0)
if [ $script_dir = '.' ]; then
script_dir="$current_dir"
fi
source_dir=$PWD
cd $script_dir
FWK_TIMESTAMP=`date +%Y%m%d_%H:%M:%S`
REPORT_TS=`date -d '1 day ago' +'%m/%d/%Y'`
TILL_DATE=`date +%m/%d/%Y`
#javac -classpath mail1.4.4.jar:activation.jar SendEmail.java
if [ $? -ne 0 ];then
echo javac failed $?
exit 1
fi
outfile=test.txt
rm test.txt
echo "<h1> Top 10 Memory Consumed Processes from $REPORT_TS to $TILL_DATE</h1>" >> $outfile
ps aux --sort -rss | head -n 10 >> $outfile
to='abc#abc.com'
mail_server='-mail.smtp.host abc.com'
param="-to $to $mail_server -from abc#abc.com"
#-mail.debug
java -cp mail1.4.4.jar:activation.jar:. SendEmail $param -subject "Top Memory Consumed Processes" -file test.txt

As I am able to see in your code,
you are saving the results of
ps aux --sort -rss | head -n 10 >> $outfile
in the $outfile.

"Too late for "-C" option" error With Perl and Shell scripts

I have a jar application that has several functions, one of which is to convert from HTML to XML. When I try to run a simple command such as:

I can't seem to figure where the problem is. And what exactly does ERROR [Thread-1] mean?
Thanks

The error comes from having -C on the shebang (#!) line of a Perl script, but not passing the -C to perl. This type of error happens when someone does
perl html2base/html2xml.pl ...
instead of
html2base/html2xml.pl ...

The error was from the the html2xml.pl script as other users rightly mentioned. I'm running ubuntu 16.04.2 system which comes with a default perl 5.22 version. And as this post mentions, using the -C option (as from perl 5.10.1) on the #! line requires you to also specify it on the command line at execution time, which I wasn't sure how to do because I was running a jar file. I installed perlbrew, instead, which I used to get an earlier version of perl and modified my perl script to:
#!/usr/bin/path/to/perlbrew/perl -W -C
# Simple HTML to XML (subset of XHTML) conversion tool. Should always produce a
# valid XML file according to the output DTD file specified.
#
# Miroslav Spousta <spousta#ufal.mff.cuni.cz>
# $Id: html2xml.pl 461 2008-03-09 09:49:42Z qiq $
This might also come in handy in setting up shell scripts when using perlbrew.
Thanks for the efforts in contribution.

String concatenating error in shell script executing

This is a wired problem confusing me for days.I want to get a class's full class name from parse the java code file in shell.We can get package name from like:
package com.android.mail.ui;
and get class name from code file path,use shell command 'basename'.
below is my shell scripts:
#!/bin/bash
get_package_name(){
java_file=$1
if [ ! -f $file_path ]; then
echo "Sorry,the java file is not exist:$1,please check"
exit 1
fi
class_base_name=`basename "$java_file" .java`
echo "class_base_name:$class_base_name"
package_name=`grep $java_file -e "^package" | awk -F " " '{print $2}' | tr ';' ' ' | sed 's/ //g'`
echo "package_name get result:$?"
echo "package_name:$package_name"
method 1,use variable concat directly
classpath_name=$package_name.$class_base_name
echo "method 1 classpath_name:$classpath_name"
method 2,use sed replace to get concat indirectly
classpath_name2=`echo "aa.bb" | sed "s/aa/$package_name/" | sed "s/bb/$class_base_name/"`
echo "method 2 classpath_name2:$classpath_name2"
}
The problem is:for some code file the result is ok,like:
"class_base_name:MailTransport package_name get result:0
package_name:com.android.email.mail.transport method 1
classpath_name:com.android.email.mail.transport.MailTransport method 2
classpath_name2:com.android.email.mail.transport.MailTransport"
for others it's output is : "class_base_name:EmailApplication
package_name get result:0 package_name:com.android.email
.EmailApplicationh_name:com.android.email
.EmailApplicationh_name2:com.android.email"
the result is totally messing and wrong.I doubt it relates the code
content,that really make sense for the result?

This happens because some of your files use Windows style CRLF (\r\n) line terminators.
Here's an example where it works, a normal Unix style LF (\n) terminated file:
$ file WorkingFile.java
WorkingFile.java: ASCII text
$ cat -v WorkingFile.java
package foo.bar.baz;
$ get_package_name WorkingFile.java
class_base_name:WorkingFile
package_name get result:0
package_name:foo.bar.baz
method 1 classpath_name:foo.bar.baz.WorkingFile
Here's an example where it fails, with CRLF line terminators:
$ file FailingFile.java
FailingFile.java: ASCII text, with CRLF line terminators
$ cat -v FailingFile.java
package foo.bar.baz;^M <--- note hidden control char revealed by -v
$ get_package_name FailingFile.java
class_base_name:FailingFile
package_name get result:0
package_name:foo.bar.baz
.FailingFilesspath_name:foo.bar.baz
To fix it, you can delete the extra carriage returns using tr -d '\r'. I switched from legacy backticks to modern $() to avoid problems with backslashes:
package_name=$(grep $java_file -e "^package" | awk -F " " '{print $2}' | tr ';' ' ' | sed 's/ //g' | tr -d '\r')

powershell for each file build a string to execute

I need to schedule a windows job to loop thru thousand of files and execute a command with the command options, the file name, and extension.
These files have an extension of *.xls in directory c:\proj. For example, one of the file is myImportantFile0001.xls, I would execute the following in powershell, manually:
PS> java.exe -classpath "C:\PROGRA~2\my1.0.2\lib/*" com.my.madsci -v --collector-url https://api.fun.my.com/ --oauth-url https://api.my.com/oauth/access --type /fileName:string/discovery:string --key /fileName:"myImportantFile0001/discovery:discovery" "C:\proj\myImportantFile0001_xls.txt"
couple of problems I've got are:
the command itself has double quotes,
the file name and extensions need to be found and converted
execute a java within powershell
So how can I loop thru the thousand of files to build a string to execute the command using powershell?

does below script helps you? i think it just strings combination.
$Commands = ls C:\Temp\*.xlsx | %{
"java.exe -classpath `"C:\PROGRA~2\my1.0.2\lib/*`" com.my.madsci -v --collector-url https://api.fun.my.com/ --oauth-url https://api.my.com/oauth/access --type /fileName:string/discovery:string --key /fileName:`"$($_.BaseName)/discovery:discovery`" `"C:\proj\$($_.BaseName)_xls.txt`""
}
$Commands
exit # remove the line if you want to execute
$Commands | %{
& $_
}

What about
PS> ls C:\Temp\*.xlsx | foreach-object {
"java.exe -classpath `"C:\PROGRA~2\my1.0.2\lib/*`" com.my.madsci -v --collector-url https://api.fun.my.com/ --oauth-url https://api.my.com/oauth/access --type /fileName:string/discovery:string --key /fileName:`"$($_.name)/discovery:discovery`" `"C:\proj\$($_.name)_xls.txt`""
}

You can do it like this:
$files = Get-ChildItem "C:\temp" -Filter "*.xls"
foreach ($file in $files)
{
$command = "java.exe -classpath ""C:\PROGRA~2\my1.0.2\lib/*"" com.my.madsci "
$command = $command + "-v --collector-url https://api.fun.my.com/ "
$command = $command + "--oauth-url https://api.my.com/oauth/access "
$command = $command + "--type /fileName:string/discovery:string "
$command = $command + ("--key /fileName:""{0}/discovery:discovery"" " -f $file.BaseName)
$command = $command + ("""C:\proj\{0}_xls.txt""" -f $file.BaseName)
Invoke-Expression $command
}

Additionally, you can also schedule it from powershell itself (Works with PS 3.0 and above)
$trigger = New-JobTrigger -Daily -At "9:00 AM"
$scriptPath = "C:\FilePath\myScript.ps1"
Register-ScheduledJob -Name "MyJob" -FilePath $scriptPath -Trigger $trigger

How can i tell Java code run the script as it was running from command line as normal user?

When i run this script manually then Browser chrome open the site in one tab (which is PERFECT exactly how i needed)
But when i run the same script using Java sample code 10 times, it open Browser but 10 times same page 10 TABs.
Q. How can i tell Java code please run it as it was suppose to be running manual execution (so that i have 1 TAB only?) ?
BASH: /var/tmp/runme.sh
(ran 1o times and still have always 1 tab as expected)
export DISPLAY=:0.0
ps aux | grep chromium-browser | awk '{ print $2 }' | xargs kill -9;
sleep 8;
chromium-browser --process-per-site --no-discard-tabs --ash-disable-tab-scrubbing -disable-translate "http://www.oracle.com" &
Java: launch 10 times that script
system("/var/tmp/runme.sh &");
public static String system(String cmds) {
String value = "";
try {
String cmd[] = { "/bin/sh", "-c", cmds};
Process p = Runtime.getRuntime().exec(cmd);
p.waitFor();
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = reader.readLine();
while (line != null) {
value += line + "\n\r";
line = reader.readLine();
}
}
catch (IOException ioe) {
ioe.printStackTrace();
}
catch (InterruptedException ie) {
ie.printStackTrace();
}
return value;
}

Java is weired sometimes. Its solved.
1( kill chromium browser before killing the java
2( after killing chromium browser then launch the java application
3( now the tab is 1 and browser is 1
BEFORE: (wrong)
export DISPLAY=:0.0
pkill java;
java -cp SystemV.jar Main.Start "boot chromium now with 1 tab and 1 browser" &
ps aux | grep chromium-browser | awk '{ print $2 }' | xargs kill -9;
chromium-browser --process-per-site --no-discard-tabs --ash-disable-tab-scrubbing -disable-translate "http://www.oracle.com" &
AFTER:
export DISPLAY=:0.0
ps aux | grep chromium-browser | awk '{ print $2 }' | xargs kill -9;
chromium-browser --process-per-site --no-discard-tabs --ash-disable-tab-scrubbing -disable-translate "http://www.oracle.com" &
pkill java;
java -cp SystemV.jar Main.Start "boot chromium now with 1 tab and 1 browser" &
echo "it works now"

Fist remove & from this line system("/var/tmp/runme.sh &");
Second, maybe since, you are using this: "/bin/sh", Java is running the script as different shell every time you invoke using Runtime?
and you are executing /var/tmp/runme.sh from the same shell everytime.
Note: /bin/sh is an interpreter and with Java Runtime you are invoking multiple instances of it to execute your script every time.
