1) Use ! for Executing the Last Command

This has saved my 30% time on average. It always happens that you fire same UNIX command multiple times within a fraction of seconds, before knowing this trick I used to use up and down arrow for finding my command and then executing them which takes some of my time but after knowing this trick I just have to remember the command name e.g. !ls will execute your last “ls -lrt” , !vim will open your last file without typing full command. computer science course computer science jobs computer science binus

Use this tip and experience it, It definitely saves loads of time and it’s also useful on shell other than bash shell (like csh or ksh) where up and down arrow generally doesn’t give you previous commands. computer science course computer science jobs computer science binus

For example, After doing ls -l stocks.txt if you want to open stocks.txt you can use the vim editor as vi !$ (last argument). computer science course computer science jobs computer science binus
