Debugging Perl in bash environment?

[giganet]

I have been thrown into managing my own leased dedicated server as of recent o:.

While installing perl scripts I have grown accustomed to debugging scripts as they error using SSH .
The problem I am faced with presently is on my new server I have setup the customer templates to allow shell access to the server in /bin/sh.

When I logo onto the server via SSH and attempt to run perl commands:
perl -x -w -T script.cgi
The server returns "bash: perl: command not found"

When I log into the server via SSH I am presented with the following line in SSH:
bash-3.00$

I am accustomed to:
[giganetwireless@erwin giganet]$

Could someone enlighten me in the proper commands and format be to debug my perl scripts?

Below is server information:
Plesk version psa v8.0.1_build80060727.19 os_FedoraCore 4
Operating system Linux 2.6.11-1.1369_FC4


Thank you for your help in this matter.

Kindest Regards

$ which perl

then use the path to perl for your script

eg, /usr/bin/perl fred.pl

Thank you for your help Paul

I tried $which perl and received "bash: which: command not found"

THen I tried "bash-3.00$ bash -x -T -w /usr/bin/perl Dream.cgi"

and received the following error

bash: -w: invalid option

Am I doing this right?

 

[PaulTEG]

[b]bash-3.00$[/b] /usr/bin/perl -wT Dream.cgi

Looks like which has been disabled
Could be worth your while to read up on setting up your login script

Thank you Paul

So I need to learn about making changes to the login script for my web-server, this is what you are referring to correct?

I have switched from bash to sh in SSH once logged onto the server:

Once I try to debug with:
sh -x Dream.cgi

I receive the following errors from a script that worked fine on another Unix server last week, why am I seeing these errors which I am assuming is causing my app to 500?

Thank you for your assistance

you're passing your scrip to the OS Shell, not perl

The reasons for your 500 errors should be visible in your Apache Logs, most likely malformed headers or file permissions
