The command "touch -c -t ${YYYYMMDDHHMM-SS} ${filename1 filename2 ---}" is used to update the timestamp of specified files to a specific date and time.
Explanation of each part of the command:
- "touch" is a command used to create empty files or update the timestamps of existing files.
- "-c" flag tells the touch command to not create any new files. It is used in conjunction with the "-t" flag.
- "-t" flag is followed by the desired timestamp format ${YYYYMMDDHHMM-SS}. It specifies the date and time in the format year (4 digits), month (2 digits), day (2 digits), hour (24-hour format, 2 digits), minute (2 digits), and second (2 digits). The timestamp can be customized by replacing the variables inside the curly braces (${YYYYMMDDHHMM-SS}) with the desired values.
- "${filename1 filename2 ---}" represents the list of files for which the timestamp needs to be updated. Multiple filenames can be included, separated by spaces.
To use this command, you would replace "${YYYYMMDDHHMM-SS}" with the desired date and time, and "${filename1 filename2 ---}" with the actual filenames you want to update. For example, if you want to update the timestamp of a file named "example.txt" to December 25th, 2020, 10:30 AM, you would use the following command:
touch -c -t 202012251030.00 example.txt
