NAME
|
|
|
|
touch - update modification date of existing file or create new file.
|
|
|
|
|
|
SYNOPSIS
|
|
|
|
touch file1 [file2 ...]
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
touch checks each file in the argument list and processes each as follows:
|
|
|
|
o If the file exists, touch sets the modification time and date to
|
|
the current time/date. It also sets the backup-needed flag.
|
|
|
|
o If the file does not exist, it creates an empty text file of that
|
|
name. The file is unlocked, with the backup-needed flag set.
|
|
|
|
Wildcard expansion is not supported outside of GNO/ME, which does its own.
|
|
|
|
Invalid filenames cause touch to exit with return code -1, printing the
|
|
offending filename before exitting.
|
|
|
|
|
|
CAVEATS
|
|
|
|
The ORCA editor does not seem to like files with length 0. It appears to
|
|
attempt to re-create the file, which already exists and is open. Use vi or
|
|
echo " " > filename. Otherwise, the file may be manipulated normally.
