Bash useful commands :D

bash.md

dirs

# display the directory stack vertically, prefixing each
# entry with its index in the stack.
$ dirs -v

# cd and push the path to the directory stack.
$ pushd /path/to/directory

# this command is the opposite of push,
# where it removes a directory from the  
# stack starting at index 0
$ popd

# Try dirs -v again to see the updated stack.
# Now you may use the stack index to refer to
# the directory or the path
$ ls -ls ~1

history

# Displays the list of commands you've performed
# prefixed with and index
$ history

# To put it in use, you may execute a command
# from that list based on the index
$ ![index] # square brackets not included

# You may also use the first two letters
# of the previous command
$ !cl # assuming `clear` was the previously excuted command

# As a precaution, you may append `:p`
# to print it first before executing it
$ !cl:p

# `!` is useful to also use the arguments
# from the previous command, e.g., `$ echo a b c`
$ echo !:3 # outputs `c`

# Now in unison
$ ![index]  / # history command index
  !:1         # history command arguments
