The 'git ignore' command modifies a .gitignore file in your path
easily. By default, it adds lines to the .gitignore found in the
root of your repository. It can, however, add lines to a gitignore
anywhere inbetween the file(s) passed in and the root of the
repository. The lines added to the gitignore can be based on
filename, extension, directory, or recursive glob.
Also, you can easily open the gitignore file using your $EDITOR
with 'git ignore --edit'.
This can make things much easier when ignore files in subdirectories.
No longer will you have to run:
echo "path/to/the/file.txt" >../../../../../../.gitignore
instead:
git ignore file.txt

+
+NAME
+----
+git-ignore - Easily add entries to your .gitignore file
+
+
+SYNOPSIS
+--------
+[verse]
+'git ignore' [--dry-run | -n] [--ext | -e] [--all-ext | -E] [--dir | -d]
+ [--all-file | -a] [--parent-level | -p <parent_level>] pathspec [...]
+'git ignore' --edit [--parent-level | -p <parent_level>]
+
+
+DESCRIPTION
+-----------
+The command modifies a .gitignore file in your path easily. By default,
+it adds lines to the .gitignore found in the root of your repository. It
+can, however, add lines to a gitignore anywhere inbetween the file(s)
+passed in and the root directory. The lines added can be based on
+filename, extension, directory, or recursive glob.
+
+Also, you can easily open the gitignore file using the $EDITOR environment
+variable.
+
+
+OPTIONS
+-------
+<pathspec>...::
+ Files to add to a gitignore. Fileglobs (e.g. `*.c`) can
+ be given to add all matching files. Also a
+ directory name can be given to add it to the gitignore
+ as well.
+
+--edit::
+ Open the appropriate gitignore file in your default editor (using the
+ $EDITOR variable). This option can be combined with `--parent-level` based
+ on your current working directory.
+
+-n::
+--dry-run::
+ Don't actually edit the gitignore(s), just show what changes
+ would have taken place.
+
+-e::
+--ext::
+ Add the relative filepath based on extension. If pathspec
+ references path/to/file.log, the added gitignore line would
+ be path/to/*.log.
+
+-E::
+--all-ext::
+ Add a global exclusion of the given extension. If pathspec
+ references path/to/file.log, the added gitignore line would
+ be **/*.log.
+
+-d::
+--dir::
+ Add the contents of the parent directory. If pathspec references
+ path/to/file.log, the added gitignore line would be path/to/*.
+
+-a::
+--all-file::
+ Add a global exclusion of the given filename. If pathspec references
+ path/to/file.log, the added gitignore line would be **/file.log.
+
+-p::
+--parent-level <parent_level>::
+ Modifications will go to a gitignore located <parent_level>
+ directories above each of the files passed in. If the number
+ of parent levels causes the directory to fall outside of the
+ root of the git repository, a warning is printed and the root
+ of the repository is used instead. Using a parent-level of 0
+ will use the gitignore in the directory of each file passed in.
+
++
+Note that the parent level is calculated for each file passed in. If multiple
+files are passed in that have different parents at a given parent level, then
+they will cause separate gitignore files to be written.
+
+
+EXAMPLES
+--------
+
+* Adds all `*.log` files under `tmp` directory
+and its subdirectories to the gitignore file found at the
+root of the repository:
++
+------------
+$ pwd
+/user/test/git_repo/src
+$ git ignore -e tmp/file.log
+------------
++
+Results in `tmp/*.log` added to /user/test/git_repo/.gitignore
+
+
+* Add the files under the `var/uploaded` directory to the gitignore above
+
++
+------------
+$ pwd
+/user/test/git_repo/
+$ git ignore -d --parent-level=1 www/var/uploaded/\*
+------------
+Results in `var/uploaded/*` added to /user/test/git_repo/www/.gitignore
