grep functionality

Dave Walley — Fri, 26 May 2000 12:32:08 GMT

Hi.

I have to extract from a file a string that contain slashes. I want to select a particular string from a file, the problem is that there are other lines that contain this string also.

The file contains the following lines among others. I only want to select the first i.e. not the line containing account.

/bkup/export
/bkup/export/account

I have tried using grep but with no sucess.

Can anyone please help me.

Dave

Dave,

Use the 'head' command to strip just the first line returned from grep, e.g.

grep '/bkup/export' filename | head -1

This should work:
grep "/bkup/export" | grep -v "/bkup/export/"

Hallo Dave

Why don't you try this

cat file_name | awk ? $1=="/bkup/export" ?

I allways prefare awk for it is much more powerfull than grep is.

best regards

Try :

grep '/bkup/export$' if lines ends w/ export

or grep '/bkup/export ' if not
