| help | unix | grep - Can I use grep to return a string with exactly n matches?
Hello,
I looking to use grep to return a string with exactly n matches.
I'm building off this:
Which prints a list of files in long format that are have an 'x' in the last file permissions position, then remove spaces between characters so that there is at most one. I now want to print just the file name. The following code does exactly that:
What I want to see if I can do is use grep instead of cut.
I figure I would need grep to be able to match a pattern exactly n times then match .*/n$.
I would want to match [[:blank:]] 8 times then match any number of characters followed by an end of line character at the end of the string.
Any ideas if I can do this with grep and the power of regular expression?
I tried various expressions on the built in dictionary to see if I could return words with say exactly 4 'a' anywhere in the word without successs.

What I would like to do is have each line that looks like this:

I’m trying to modify someone perl script to fix a bug. The piece of code checks that the zone name you want to add is unique. However, when the code runs, it finds a partial match using grep, and decides it already exists, so the “create” command exits.
$cstatus = `${ZADM} list -vic | grep... (3 Replies)
