[Solved] how Execute a Perl Script from any location on the machine

Shell Programming and Scripting
1

hi guys,

i have a query, i wrote a perl script that will collect cpu statistics

Scripts/myScripts/
cpu.pl

i want to make this file so that i can run it from any location on any drive,
without giving the path explicitly.

like

$/home/ravi/perl
cpu.pl

i tried this by adding the following line to my file

system("cd /Scripts/myScripts") or die "Can't change the directory";

but its not working....

can someone help me with this issue.....

thanks and regards

Include current directory "." in PATH variable.

export PATH=.:$PATH

Or put cpu.pl in /arbitrary/directory, and

export PATH=/arbitrary/directory:$PATH

You may be considering adopt the first suggestion, but you need to read this post before you take action.

no its not working....same issue....

i forgot to mention one more thing my source file is at location

$/home/ravi/perl

im supposed to execute at location

$/home/ravi/Scripts/myScripts

so everytime when i want to execute i have to go "$/home/ravi/Scripts/myScripts" and execute

so i want to make it so that i need not go to "$/home/ravi/Scripts/myScripts" location everytime to execute.

from any directory i want to execute it as just cpu.pl

SORRY FOR MENTIONING THESE DETAILS

Sorry, I forgot to mention that you need to source the file in which you export the PATH variable.
Let's say you export your PATH variable in "/home/ravi/.bashrc", you need to do this after that:

. /home/ravi/.bashrc
or
source /home/ravi/.bashrc

sorry,
i din understand....
can u elaborate on this....

location of my code is "$/home/ravi/perl"

and everytime i need to execute at "$/home/ravi/Scripts/myScripts"

and my file is "cpu.ksh"

Use your favorite editor and open /home/ravi/.bashrc
At the end of that file, you add this line:

export PATH=/home/ravi/perl:$PATH

Save and exit.
And execute:

source /home/ravi/.bashrc

And run:

cpu.pl

i am getting this error

-ksh: .[1]: bind: not found [No such file or directory]

In Korn Shell you may need to use .(dot) to source files. I am using Bash Shell, am not sure.
Try this:

.   /home/ravi/.bashrc
