Error q : Command not found on Vim

Question

I created a bash script :

#!/bin/bash 
su root -c vim $1 -c ':%s/^M//g' -c 'wq'

My script has to remove all the ^M (carriage return on Windows) on my file, then save it.

When I execute my script it returns :

/sequenceFiles/Sequence1.seq: wq: command not found

Does someone know why ? Thanks for your help.

Answer 1

The -c is seen by su , not vim , and the shell complains about the unknown command.

You need to pass the command as one argument to su :

su root -c "vim $1 -c ':%s/^M//g' -c 'wq'"

Answer 2

man su says:

`-c COMMAND'
`--command=COMMAND'
     Pass COMMAND, a single command line to run, to the shell with a
     `-c' option instead of starting an interactive shell.

Try

su root -c "vim $1 -c ':%s/^M//g' -c 'wq'"

Answer 3

虽然你可以用vim做，但考虑更简单：

perl -pi -e 's/\r\n/\n/' file
