I dun't have any Linux/Unix system with me right now, so please check the syntex.

Thanks
Good try....But then tell me what will you do when the numeric length varies that means it could be of sometimes 7 characters, sometimes more then 7 characters and sometimes less then that. At that time your given option would fail, because immediately the numeric string there is a character attached, presently its 'c'.
inode 1138932c(mqsiadm)
inode 1257904c(mqsiadm)

Now tell me !!

Smilie As well I told you that currently I dun have any *NIX box with.
There is one logic in my mind

After the Filter we can use "c" as a delimeter and then cut the firt Filed.
Try It !!

cut -d ' ' -f 2 <file_name>|cut -d 'c' -f 1

Hey,

But what then if even the delimiter is other then c, because i am getting variable input into the file !! Can you place more then 1 delimiters then ??

Anyways as you don't have unix comp. now in front of you, leave it as of now, i got the o/p.

Thanks buddy !!Smilie

Hi,
I think think this is ok.

Code:
echo inode 1138932c | sed 's/[a-z,A-Z]//g'
