Shell Programming and Scripting

hi,
In my script, i wrote a line like this : ls -lrt tpa* > x.xls
while executing the script, it showing o/p as "tpa*: No such file or directory" because there is no files starts with tpa*

now, instead of server showing this msg, i want my scritpt to display as : "No jobs available which starts with tpa*"

so how can i change my script

Code:

ls -lrt tpa* > x.xls 2>/dev/null
if [ $? -eq 2 ]; then echo "No jobs available which starts with tpa*"; fi

You would have to redirect 'stderr' to a file for the 'ls' command so that the message does not display when there is an error in the script.

After running the command, you can either check the $? variable for a non zero result and print your own error, or check the size of the file you redirected stderr to, to see if it is > 0.

Alternatively, you may want to check the actual contents of the file you directed 'stderr' to as the error may not be the one you mentioned, but something else (depending upon what actually caused the error) and handle each different error appropriately.

Code:

ls -lrt tpa* > x.xls 2>/dev/null || echo "No jobs available which starts with tpa*"

Or like

Code:

if ! ls -lrt tpa* > x.xls 2>/dev/null 
then
       echo "No jobs available which starts with tpa*"
       exit 0
fi

Thanku,
here i have one more question. In my script, i wrote a line like this: ls -lrt fva* >x2.xls

while executing the script, it showing o/p as " fva*: list is too big" so it is not creating the file and not executing the other lines of script.

so plz suggest me how can i create this file even if the sise is too big?

Code:

files=fva*
if [ "$files" = "fva*" ] ; then
       echo "No jobs available which starts with fva*"
       exit 0
fi
find . -maxdepth 1 -name "fva*" > x.xls

Try this

Code:

find /path  -name fva* -exec ls -lrt {} \; > x2.xls
