Just wanted to share an alias I have in use and found it useful again. It's a simple wrapper around xargs, which I always forget how to use properly, so I set up an alias for. All it does is operate on each line on stdout.

The arguments are interpreted as the command to execute. The only thing to remember is using the {} as a placeholder for the input line. Look in the examples to understand how its used.

# Pipe each line and execute a command. The "{}" will be replaced by the line.
#
# Example:
#   cat url.txt | foreach echo download {} to directory
#   ls -1 | foreach echo {}
#   find . -maxdepth 2 -type f -name 'M*' | foreach grep "USB" {}
alias foreach='xargs -d "\n" -I{}'

Useful for quickly operating on each line of a file (in example to download from list of urls) or do something with any stdout output line by line. Without remembering or typing a for loop in terminal.

Don't steal people's content, at least crosspost properly.

See the link in this users profile which explains why

I know why. The OP decided to post where they decided to post, it's frankly unethical to steal OP's shit and not crosspost properly.
