Re: sed question

Thursday, 21 July 2016

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.
