CHDATE(1) General Commands Manual CHDATE(1) NAME touch, chdate - set modification or access date of a file SYNOPSIS touch [ -c ] file ... chdate [ -am ] date file ... DESCRIPTION Touch attempts to set the modification time of the files to the current time. If a file does not exist, it will be created unless option -c is present. Chdate sets the access and modification times of files. The date com- prises two or more arguments: a month (3 letters or more), a day num- ber, an optional time in hour:min[:sec] form, and an optional year. A missing year means a time in the last 12 months. The options are -a Change the access time only. -m Change the modification time only. Chdate knows how to carry between fields of a date. Only a file's owner or the super-user can change its date.
