finding multiple occurances of a pattern


Hello,
I wish to find multiple occurances of the pattern "Connection <some string> = {".

Here except <some string>, all the characters in the
above pattern are constant.and I wish to find all such patterns in a file.

Please help me to solve this.

Thnks.

$ sed -n -e '/Connection \(.*\) = {/p' pattern_file

You can use the grep command.
If all of the patterns occur on the same line and are not split, that makes things easier.
grep 'Connection [[:alnum:]]-:]* = {' filename

Look at what characters can occur in the <some string>. If they don't include a space or equals sign, you can use:
grep 'Connection .* = {' filename

If the pattern can be split across one or more lines, then you may need to use sed

If possible, also try kfind - seems to be a good GUI solution.

Edit - doesn't appear to work for string occurences in plain text files - bummer!
