Needed to add a bunch of files to my (mercurial) hg repo and realized that a command I use all the time in subversion (svn) repos.
hg st | grep ? | sed 's/? *//' | xargs hg add
Break it down for ya. Remember the "|" unix character takes the results of stdout and pipes that as the inputs to the next chain in the command. For the purposes of explanation, assume I were to create a file called testfile.js in the "js" directory in my repo directory.
1. hg st - this displays the files in an hg repo that are currently not versioned in the repo. Results are sent to stdout.
2. grep ? - This looks at each line and returns it valid if there is a ? in the string.
3. sed 's/? *//' - sed is an awesome text tool for performing operations on text, in this case a executing a regex on each line that removes that ? from the text. This is important because the next command does not recognize "?" as in the filename.
4. xargs hg add - Finally, we execute the command on the sanitized string.
