dos2unix broke my script, but it works in dos format? (unix2dos)
My script is designed to first close a screen, for example named 'name1', by sending 'exit' then sending a return key, then open up a new one of the same kind. I do this to prevent a duplicate from running.
However running it only works when it it's in dos format (vim shows [dos] at the bottom while editing), and it also gives those expected $'r': command not found errors.
This is the script (with the last line truncated):
#!/bin/bash
screen -S name1 -X stuff 'exit'`echo -ne '15'`;
sleep 3;
screen -A -m -d -S name1 /dir/to/program -options ...
Here is what happens when I run it when it's in unix format.
$ bash /dir/to/script.sh
No screen session found.
After this, the final screen command is not run, as I check my processes or use screen -r and it's not there.
After using the unix2dos command on the shell script, it has some line errors, but it actually works:
$ bash /steam/gmodsandbox2start.sh
No screen session found.
/steam/gmodsandbox2start.sh: line 2: $'r': command not found
/steam/gmodsandbox2start.sh: line 3: $'r': command not found
/steam/gmodsandbox2start.sh: line 4: $'r': command not found
/steam/gmodsandbox2start.sh: line 5: $'r': command not found
After this, the screen is up and running and I can see it in my processes.
So my question is, what is wrong with my shell script? I would like to have it as a standard unix file and work at the same time. This also is making me genuinely curious as to what may be causing this.
