如何在命令行上的每个命令的末尾添加 ls -la？

Question

I am constantly running ls -la after cd 'ing into folders as I often work on file trees that I'm not familiar with.

This is getting tedious and I would like someway to add ls after each time I press enter so I can always see the list of files and folders when I change directory.

I couldn't find much support on google as I wasn't sure what to google.

Answer 1

You can set

PROMPT_COMMAND='ls -la'

It runs the command before showing the prompt, ie after it runs the command you entered in the command line. In other words, if you're in a directory with many files, you won't see any output of your commands, as it will scroll out because of the prompt command. Maybe using something like

PROMPT_COMMAND='ls -la | head -n10'

might be better.

Answer 2

Create a function in your.bashrc like

mycd() {
  cd "$*" && ls -la
}

Edit:
Better is supporting different options/arguments with

mycd() {
  cd "$@" && ls -la
}
