You may also have to convert it to UNIX format with `dos2unix file.txt` — understorey, May 10 '22 at 09:12

Just do bash file:

$ cat file 
date
echo '12*12' | bc

$ bash file

In case of aliases just run bash -i file

No need to worry about file extensions or execution rights.

This works with native commands but I have an *alias* stored in my file and this way not working. I got error: "No command 'mycm' found ...". Are there another way for it? – Hank Phung Mar 08 '17 at 11:05

In a Terminal just type:

bash path/to/my/file.txt

And you will get each lines executed.

just change the extension of the file to .sh

add /bin/bash at starting of the file

change the permission of the file to executable

than simply run ./filename.sh command in command line. all the commands in the file will be executed

If who made the question doesn't how to execute commands stored in a file, I doubt he will able to rename or change permission without any extra explanation. – Rubens Mariuzzo Nov 26 '12 at 15:38
If he needs executing command, then obviously he knows something about the commnadline(though I don't expect he knows very mush about shell). I think working in shell is a immense beauty and nice. I told him about the very basics of shell programming. In stackoverflow, some coding is always been wellcomed. Then If I say him about the coding in shell, then what is wrong?? and why the dwnvote? – Debobroto Das Nov 27 '12 at 02:28

Change the extension to .sh and for the first line #!/usr/bin/env bash and as someone else said chmod +x

Changing the extension is not important nor relevant. – Rubens Mariuzzo Nov 26 '12 at 15:36
