I have a large set of files in which I need to replace a full URL scheme. Some filenames contain spaces. After much searching and rial and error, this is the closest I've come:

find /somedir -type f -print0 -exec sed -i'' -e 's#http\\:\\/\\/domain.com#https\\:\\/\\/www.domain.com#g' {} +

The resulting file has the scheme http: removed, leaving the // - i.e. '//www.domain.com'

Additionally, a NEW file is created, appending -e to the filename. - i.e. some file.php-e which obviously unwanted.

While this would certainly suffice (after removing the *-e files, the OCD in me really wants to know how to do this correctly. Note: I'm working locally on a Mac but will also be performing this on linux.

Any ideas are greatly appreciated!


Solution 1: One way is to use find with xargs:

find /dir -type f -print0 | xargs -0 sed -i 's#http://domain.com#https://www.domain.com#g'

Solution 2: Another one would be to use find with -exec, very similar as in your question:

find /dir -type f -exec sed -i 's#http://domain.com#https://www.domain.com#g' {} +

Both solutions will call sed with mutiple files as arguments. So sed is not called once for every file, but for every set of files.

Solution 3: Instead of sed, you could also use perl for the search-replace-job:

perl -i -pe 's#http://domain.com#https://www.domain.com#g' file

Combined with the find/xargs command:

find /dir -type f -print0 | xargs -0 perl -i -pe 's#http://domain.com#https://www.domain.com#g'
  • unfortunately the first two error with: command c expects \ followed by text. The last one works on a specific file but how do I do it recursively (keeping in mind possible spaces in filenames/dirs)? – Chris Chapman Jul 21 '15 at 16:41
  • @ChrisChapman Just combine it with the find/xargs command: find /dir -type f -print0 | xargs -0 perl -i -pe 's#http://domain.com#https://www.domain.com#g' – chaos Jul 21 '15 at 17:30
  • Ding Ding Ding! - we have a winner! Thanks a ton. Perl was a jillion times faster too. – Chris Chapman Jul 21 '15 at 17:43
