I\'m still new to Unix. Is it possible to run multiple commands of Unix in one time? Such as write all those commands that I want to run in a file, then after I call that file,
Short answer is, yes. The concept is known as shell scripting, or bash scripts (a common shell). In order to create a simple bash script, create a text file with this at the top:
#!/bin/bash
Then paste your commands inside of it, one to a line.
Save your file, usually with the .sh extension (but not required) and you can run it like:
sh foo.sh
Or you could change the permissions to make it executable:
chmod u+x foo.sh
Then run it like:
./foo.sh
