Pipex email

A classic Unix command!

pipex is a command-line utility that allows you to pipe the output of one command to another, similar to the | character. However, pipex is more powerful and flexible than the | character, as it allows you to specify the input and output files, as well as the commands to run.

Here's the basic syntax of pipex:

pipex [options] command1 [args] | command2 [args]

Where:

• command1 is the first command to run
• command2 is the second command to run
• args are the arguments to pass to each command
• options are optional flags that can be used to customize the behavior of pipex

Here are some examples of how you can use pipex:

1. Simple piping:

   pipex ls -l | grep foo

   This will run the ls command with the -l option, and then pipe the output to the grep command with the pattern foo.

2. Piping with input and output files:

   pipex cat input.txt | grep foo > output.txt

   This will run the cat command to read the contents of the input.txt file, pipe the output to the grep command with the pattern foo, and then write the output to the output.txt file.

3. Piping with multiple commands:

   pipex ls -l | grep foo | sort -n

   This will run the ls command with the -l option, pipe the output to the grep command with the pattern foo, and then pipe the output to the sort command with the -n option to sort the output numerically.

pipex is a powerful tool that can be used to automate complex tasks and workflows. It's especially useful when you need to chain together multiple commands to process data or perform complex operations.

As for sending an email using pipex, you can use the mail command as the second command in the pipeline. For example:

pipex ls -l | mail -s "File list" [email protected]

This will run the ls command with the -l option, pipe the output to the mail command with the subject "File list" and the recipient [email protected].
