How can i check my code .. - Shell Programming and Scripting

Dastard · #1 08-08-2006

HTML Code:

#!/bin/sh
#For Daily Routine
echo 'Checking in Progress ...'
echo > status.txt
echo >> status.txt
for i in IVR011 IVR012 IVR021 IVR022
do
echo >> status.txt
echo ' ****** '$i ' *******' >> status.txt
echo >> status.txt
rsh $i df -k >> status.txt
echo >> status.txt
rsh $i sar 1 5 >>status.txt
echo >> status.txt
rsh $i ppaid check all >> status.txt
echo >> status.txt
done
echo 'done'

Well given above is my lil effort which is quite self explanatory , now i need to ask is .. is there someway that i can check my code ( for errors ) before running it on actual server ?
and also since in this code i m using "rsh" .. which do sometimes prompt for username and password .. can i add these two parameters in my code with every "IVR"..if yes .. how ?
waiting for reply .
regards

I don't remember about varsions of sh, but I think at some point more modern Bourne shell supports:

Code:

#place this just below the magic number (1st) line
set -n

This just checks syntax, it executes nothing. If it does not work for you change to #!/bin/ksh for a test.

The HPUX 11.0 version of /bin/sh supports it at any rate... and it was first shipped in the 1990's.

Well i just checked that how many shells i have on my system . it prompted like
/sbin/sh
/bin/tcsh
/bin/true

and i work in "tcsh" which is C shell perhaps ... does this shell support any sort of debugging ... besides .. does this code make a logic to you ... i mean i m just thinking hard that if i could check it on system or not ..

I don't know csh or tcsh.

set -n is designed to check syntax - what you asked. You have sh which will probably do. Try it. Try it at the command prompt when you are in sh.

Code:

sh
set -n
exit

If set -n is not allowed, then you will get an error after the set -n command. It should be okay...

Thanks .. this is fine and fortunately i have found a workstation to play with aswell :-D

HTML Code:

rsh $i df -k >> status.txt
echo >> status.txt

Now just take look at these two lines of code .. they are working fine ..but i want a lil more .. well after rsh it should follow these steps
su - ops
cd severe
show tsp

and store the output of "show tsp" in same 'status.txt'
