Shell Programming and Scripting

I have a file in which there are strings given below:

inode 1138932c(mqsiadm)
inode 1257904c(mqsiadm)

I want to get the nos. only form these.

The o/p should be
1138932
1257904

How to filter this out ??

You can do by "awk" utility or by "cut" command.

You can also use tr

Code:

tr -dc '0123456789' < input.file

Sanjay,

I know what are the filtering tools ..but then i want the solution in terms of syntax based on the query given by me.

Thanks anyways for your suggestion !!

Hey, I know you have used following one..
tr -d
Deletes each character from standard input that is contained in the string specified by String1. Notes:
1 When the -C option is specified with the -d option, all characters except those specified by String1 will be deleted. The contents of String2 are ignored unless the -s option is also specified.
2 When the -c option is specified with the -d option, all values except those specified by String1 will be deleted. The contents of String2 are ignored unless the -s option is also specified.

I have contents in the file...

/clocal/mqbrkrs/user/mqsiadm/sanjay:
inode 1138932c(mqsiadm)
inode 1257904c(mqsiadm)

And when I run command given by you then I get following..
47940411389321257904


Don't know from where its been generated ?

Varun,
Try this one !!
cut -d ' ' -f 2 <file_name>|cut -c1-7

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

Thanks

Perhaps,

Code:

[~]$ 
echo "inode 1138932c(mqsiadm)
inode 1257904c(mqsiadm)" | tr -dc "[:digit:]\n"
1138932
1257904
[~]$
