Touch -- set file modified and/or accessed time
touch( $filename ); # update both to now
touch( $filename, $access, $modify ); # update both
touch( $filename, :$access!, :$modify! ); # update both
touch( $filename, :$access!, :only! ); # update access only
touch( $filename, :$access! ); # update access, set mtime to now
touch( $filename, :$modify!, :only! ); # update modify only
touch( $filename, :$modify! ); # update atime, set atime to now
Touch is a wrapping of Cs utimensat call. It allows the
setting of file access and modify times.
The Instant type is used to express all time values seen
in Raku. Instants being passed to C representing
times in the years from 1939 to 2285 inclusive are valid.
The formal limits are in $MIN-POSIX and $MAX-POSIX as
posix time values.
When an access or modify argument is absent, its default is now.
Use the :only flag to leave the absent timestamp unchanged.
All given arguments must be defined. :ONLY is deprecated.
Exceptions have been added.
Symlinks are always followed. Acting on symlinks directly is not
supported. This mirrors Raku's behavior when when reading file
Alpha code. Run the tests. If tests fail, you may increase the
lag allowance for writing and reading back a timestamp. Set $TESTLAG
in the environment. 0.01 second is the default.
The calling interface is not to be considered stable yet. There
are no plans to change. Feedback is welcome, It is supposed to be
accomodating and easy.
