How to call a perl script from Linux shell script

[ISHAVERMA]

Hello All,

We are going to migrate from Unix to Linux . In unix we can directly call the perl script by specifying the name . But when we call perl script in the same way in Linux from shell script , It gives error like "scriptname : not found [No such file or directory]" .

So I want to know how we can call the perl script from Linux shell script sothat this error is rectified and perl script runs as expected.

Thanks in Advanve !!

Hi ISHA,

On your linux console do a command "which perl" which will give you certainly the path of your perl executable as "/usr/bin/perl" (though the path of perl executable may differ, depending upon where your perl executable has been installed, generally it should be as /usr/bin/perl)

You can then implement this into your shell script by writing the 1st line in your shell script as:
#!/usr/bin/perl -w

#Then try using below line in your shell script as below, you can also
#use the absolute path of your perlscript.pl
/usr/bin/perl perlscript.pl

Try this...and let me know, if the problem still resists.

Thanks

#!/bin/bash

# test.sh

# Simple execute Perl script from Bash sckrip.
# Executed srcipt do work as expected
#
# hello.pl source:
#
# #!/usr/bin/perl

# print "Hello World!\n";


clear
exec ~/00/hello.pl

# Terminal is cleared and
# after Perl script is done, string: Hello World! is writed.
# Perl script should have execute attribute: chmod ug+x ~/00/hello.pl

So, actualy You don't need nothing special to execute Perl scripts from Bash script. Try to find out a problem source. Check Perl script attributes.

Pankaj and Neirons thanks a lot , because of the information provided by you I could resolve that problem by calling the perl script as below from the shell script:

/user/bin/perl perlscriptname

Thanks again !!!
