script to swap two files

rated 0 times [ 11] [ 0] / answers: 1 / hits: 5857 / 3 Years ago, wed, august 4, 2021, 5:46:17

one thing that always drove me crazy is the need to do

 mv file1 tmp

 mv file2 file1

 mv tmp file2

in oder to swap 2 filenames.

what do you guys use to swap 2 files? Are there any standard script for swaping?
something like sw file1 file2 would be nice

Suggestion would be to add to bash a function that will swap two files:

nano .bashrc

paste in at the bottom of the file:

function swap()         

{

  if [ $# -ne 2 ]; then

    echo "Usage: swap file1 file2"

  else

    local TMPFILE=$(mktemp)

    mv "$1" $TMPFILE

    mv "$2" "$1"

    mv $TMPFILE "$2"

  fi

}

either logout/login or run:

source .bashrc

To swap two files run:

swap x y

where x and y are your file-names

source
