NAME

touch − update access and modification times of a file

SYNOPSIS

touch [ −amc ] [ mmddhhmm[yy] ] files

DESCRIPTION

The touch command causes the access and modification times of each argument to be updated.  The file name is created if it does not exist.  If no time is specified [see date(1)], the current time is used. The −a and −m options cause touch to update only the access or modification times, respectively (default is −am).  The −c option silently prevents touch from creating the file if it did not previously exist. 

The return code from touch is the number of files for which the times could not be successfully modified (including files that did not exist and were not created). 

NOTE

You need to use touch ./nnnn to create a file with an all-numeric name in the current directory.
