So, you
want to copy files from one folder to another folder and change both the source
and destination timestamp?
Linux can
easily change or modify the timestamp with ‘touch’ command.
A one liner
command with the help of ‘pipe’ to pass the arguments and ‘xargs’ to execute
multiple commands in a single line can easily accomplish this task.
Command
below will copy the files in the current directory where ‘ls’ command is
executed to the directory ‘xfiles’, timestamp will be changed to 7 hours less
from the current time.
ls | xargs -I % sh -c 'touch -d "7 hours ago" %; cp -p % ./xfiles';
-p option is important to preserve the modified
timestamp
Note: the
above command will change the timestamp for both source files and destination
files.
Command
below will change the source timestamp, but the destination timestamp will be
the date and time that the command was executed.
ls | xargs -I % sh -c 'touch -d "2 Aug" %; cp % ./x';
Notice,
that the -p option is omitted on the cp command; thus the source files
timestamp will be changed while the destination timestamp will be the time and
date that the command is executed.
Command
below will change the timestamp of the files and folder in a current directory
to 1 Aug.
ls | xargs -I % sh -c 'touch -d "1 Aug" %’;
Cheers! Till next time..
