Need help with Regular Expressions

Hi,

In ksh, I am trying to compare folder names having -141- in it's name.
e.g.: 4567-141-8098 should match this expression '*-141-*'
but, -141-2354 should fail when compared with '*-141-*'
simlarly, abc should fail when compared with '*-141-*'
I tried multiple things but nevertheless, everything failed.
It would be great if someone can help me on this.

Thanks and Regads.

Show what you have tried and how they failed and we can point you in the right direction.

I beleive I can do something with grep, but just not getting any directions on how to go ahead.
Thanks for your help.

Thanks and Regards

grep on '-141-' should be sufficient. The backslash or the double minus sign prevents grep to treat the regexp as an option, but not all versions of grep support them both:

Code:
grep -- '-141-'

or:

Code:
grep '\-141-'

Thanks a tonne for that help. Besides the pattern issue, there was anoher mistake that I did. I configured one wrong paramter in the if condition and as it was and operation, it was bound to fail. Smilie
Thanks very much for your help and time. Much appreciated !!

Thanks and Regards.

Hi Guru's,

Following approach worked for me.

Quote:
LD_CLIENT='*-141-*'
ls -ld $USR_HOME/$LD_CLIENT | grep $PARAM_SIX
SRC_LD=$?
ls -ld $USR_HOME/$LD_CLIENT | grep $ID_DEST
DEST_LD=$?
if [ $SRC_LD -eq 0 -a $DEST_LD -eq 0 ]
then
echo 'It works'
else
echo 'Keep trying'
fi
Thanks once again
