Temporary files are used to temporarily store data that the operating system needs temporarily during operation and will disappear when no longer needed. they will disappear on their own after reboot.
This command in Linux allows the user to make a temporary file or directory in the tmp folder. Now we’re gonna teach you to use the mktemp command in Linux.
The syntax of the mktemp command
$ mktemp [option] … [template]
You have just created a temporary file in the tmp directory. And the filename is also generated automatically.
Usage: mktemp [OPTION]... [TEMPLATE] Create a temporary file or directory, safely, and print its name. TEMPLATE must contain at least 3 consecutive `X's in last component. If TEMPLATE is not specified, use tmp.XXXXXXXXXX, and --tmpdir is implied. Files are created u+rw, and directories u+rwx, minus umask restrictions. -d, --directory create a directory, not a file -u, --dry-run do not create anything; merely print a name (unsafe) -q, --quiet suppress diagnostics about file/dir-creation failure --suffix=SUFF append SUFF to TEMPLATE. SUFF must not contain slash. This option is implied if TEMPLATE does not end in X. --tmpdir[=DIR] interpret TEMPLATE relative to DIR. If DIR is not specified, use $TMPDIR if set, else /tmp. With this option, TEMPLATE must not be an absolute name. Unlike with -t, TEMPLATE may contain slashes, but mktemp creates only the final component -p DIR use DIR as a prefix; implies -t [deprecated] -t interpret TEMPLATE as a single file name component, relative to a directory: $TMPDIR, if set; else the directory specified via -p; else /tmp [deprecated] --help display this help and exit --version output version information and exit Report mktemp bugs to firstname.lastname@example.org GNU coreutils home page: </software/coreutils/> General help using GNU software: </gethelp/> Report mktemp translation bugs to <http://translationproject.org/team/> For complete documentation, run: info coreutils 'mktemp invocation'Code language: HTML, XML (xml)
Creating a temporary directory
To do this. Let’s add the option -d into the command:
$ mktemp -d
Name the temporary file
If you want to name the temporary file, add more than 3 X’s at the end. For example:
$ mktemp newfileXXX
Or you can name the temporary directory:
$ mktemp -d newdicXXX
Adding the suffix
To do this. Let’s add the option –suffix into the command. For example:
