When using the sed command in Linux, it is common to store the temporary file in the default temporary file directory, which is usually specified by the TMPDIR environment variable. However, sometimes it is necessary to store the temporary file in a different directory for various reasons, such as insufficient disk space in the default temporary file directory or for security purposes. In this case, it is necessary to set a custom temporary file directory for the sed command.

To set the temp file directory for sed command in Linux using the -T option, follow these steps:

In this example, the -i option is used to modify the file "file.txt" in place. The -T option is used to set the prefix of the temporary file names to "sed".

In this example, the suffix of the temporary file names is set to ".bak".

That's it! Now you know how to set the temp file directory for sed command in Linux using the -T option.

To set the temp file directory for the sed command in Linux using the TMPDIR environment variable, follow these steps:

Open the terminal and type the following command to set the TMPDIR environment variable:

Replace /path/to/temp/dir with the actual path to the directory where you want to store the temporary files.

Now, you can use the sed command with the -i option to edit the file in place and the -e option to specify the sed script. For example:

This command will replace all occurrences of foo with bar in the file /path/to/file.txt using the temporary files stored in the directory specified by the TMPDIR environment variable.

You can also use the sed command with the -s option to specify the separator character for the sed script. For example:

This command will replace all occurrences of foo with bar in the file /path/to/file.txt using the temporary files stored in the directory specified by the TMPDIR environment variable and the separator character |.

Finally, you can check the content of the temporary files stored in the directory specified by the TMPDIR environment variable using the cat command. For example:

This command will display the content of all temporary files starting with sed in the directory /path/to/temp/dir.

That's it! You have successfully set the temp file directory for the sed command in Linux using the TMPDIR environment variable.

To set the temporary file directory for the sed command in Linux, you can use the TMP or TEMP environment variables. Here are the steps to do it:

This command will create a temporary file in the directory specified by the TMP or TEMP environment variable, and then replace the original file with the modified temporary file.

Here's another example that uses a variable to store the temporary file path:

This command will create a temporary file in the directory specified by the TMP_DIR variable, write the modified contents to the temporary file, and then move the temporary file to replace the original file.

That's it! Using the TMP or TEMP environment variables is a simple and effective way to set the temporary file directory for the sed command in Linux.
