For the examples we’re going to use the seq command: # Print 3 numbers seq 3 # 1 # 2 # 3 # xorgs wil print the numbers "inline" seq 3 | xargs # 1 2 3 # -n will use a max number of arguments per command line seq 3 | xargs -n 2 # 1 2 # 3 # -I is used to replace {} with the argument from the previous command seq 3 | xargs -I {} echo 'number {} printed' # number 1 printed # number 2 printed # number 3 printed # Create 1, 2, 3 folders seq 3 | xargs mkdir # Remove 1, 2, 3 folders seq 3 | xargs rm -rf
