## Bash command: touch
|
|
|
|
**Change timestamps of files.**
|
|
**Quickly create new files.**
|
|
|
|
```
|
|
touch [options] filename
|
|
```
|
|
|
|
Creates empty file if filename does not exist or modifies timestamps of existing files to current time.
|
|
|
|
This command can create multiple empty files in one line of code.
|
|
|
|
Commonly used options:
|
|
- `-t` change timestamp to specific date ((YYYYMMDDHHMM.SS)) instead of current time.
|
|
- `-r` use timestamp from first file to second file.
|
|
- `-a` In case you want to only change the access time, use the -a command line option.
|
|
- `-m` Similarly, if the requirement is to only change the modification time, use the -m command line option.
|
|
Examples:
|
|
```
|
|
touch -t YYYYMMDDHHMM.SS filename
|
|
touch -r file1 file2
|
|
touch -am file3
|
|
```
|
