The syntax for the contents of a
P4IGNORE file is not the
syntax. Instead, it is similar to that used by other versioning
- Rules are specified using local filepath syntax. Unix style paths will work on Windows for cross platform file support.
#character at the beginning of a line denotes a comment.
You can escape the
#comment character with a backslash (
\). This allows filenames beginning with
#to be ignored.
!character at the beginning of a line line excludes the file specification. These exclusions override rules defined above it in the
P4IGNOREfile, but may be overridden by later rules.
\on Windows) character at the beginning of a line causes the file specification to be considered relative to the
P4IGNOREfile. This is useful when the rule must apply to files at particular depots of the directory tree.
\on Windows) character at the end of a line causes the file specification to only match directories, and not files of the same name.
*wildcard matches substrings. Like the Helix server wildcard equivalent, it does not match path separators; however, if it is not used as part of a path, the directory scanning nature of the rule may make it appear to perform like the Perforce "
**wildcard matches substrings including path separators. It is equivalent to the Helix server "
..." wildcard, which is not permitted.

The first match is used when figuring out what to ignore.

and reconcile operations. For example, the following command, lets you
know which line of the
P4IGNORE file is being used to ignore
$ p4 ignores -v -i mypath
