Re: sed question

[bruce <badouglas@xxxxxxxxx>]

Hey Tudor, and others..

The test sed I posted works for doing a search/replace of the text inside the parens...

> foo('txt')
> foo("txt")

however.. if i wanted to craft a sed that uses the entire >>foo('txt')<< as the search.. then I run into the need to handle the parens.. and that's the issue..

this doesn't work

sed -i 's/foo('txt')/foo('/dir1/txt') /' *files.dat
sed -i 's/foo\('txt'\)/foo\('/dir1/txt'\)/' *files.dat

thanks

Try like this:

 cat /tmp/1.txt
foo('/dir1/txt')

 sed -e 's#'txt'#'dir1/txt'#' /tmp/1.txt
foo('/dir1/dir1/txt')

Or:
sed -e  's/'txt'/'dir1\\/txt'/' /tmp/1.txt

You need to escape the / in the replacement string.
