On a linux system, change the dos format file to unix

For example, there is a file convert.sh edited on windows (dos text format), and then uploaded to the linux system.

View the format of convert.sh on the linux system

vi convert.sh

On the vi command line, enter

: set ff

to output the file format of the file, for example: fileformat=dos

If you want to convert the format to unix ,

you can enter the command

: set ff=unix

and then enter the command

: wq

save and exit, this time the file format has been converted to unix
