Top Forums UNIX for Dummies Questions & Answers spacing question Post 72579 by zazzybob on Sunday 22nd of May 2005 10:30:08 AM

Code:
s/^.*(cool).*$/\1/

s/ - substitute
^ - beginning of line
.* - any number of anything
(cool) - if we find cool, remember that we find it - same as \(cool\) in sed
.* - any number of anything again
$ - end of line
/\1/ - replace the whole line with whatever we remembered

This is very "conceptual" - read a good regex book for more - you can have multiple \( \) and then shuffle the order of things about, e.g.
Code:
$ echo "three words here" | sed 's/^\([^ ]*\) \([^ ]*\) \([^ ]*\)/\2 \3 \1/'
words here three

Again, a full regular expression tutorial is beyond the scope of any thread... Google will be your friend here...

Cheers
