NAME
touch - update date last modified of a file
SYNOPSIS
touch [ -c ] file ...
DESCRIPTION
_T_o_u_c_h attempts to set the modified date of each _f_i_l_e. This is done by reading a character from the file and writing it back.
If a _f_i_l_e does not exist, an attempt will be made to create it unless the -c option is specified.
