How to use cygwin to run bash script

Hi, all,

I try to run a quite simple bash script mytest.sh in cygwin, it's content is:

#!/bin/bash

echo "It is my first bash shell"

there are three lines in the script. The second line is blank line.

When I run it use command: bash c:/mytest.sh,
I got error " command not foundest.sh: line 2:", I wonder if it is not allowed to have a blank line in bash script.

Another question is when I run it use command ./c:/mytest.sh, I got error "bash: ./c:/mytest.sh: no such file or directory. " but I think we can run script by ./filename, is that right?

I am a novice of Unix and cygwin, any help would be appreciated.

Thanks,
Jenny

i've never used cygwin... but what is about the path to the shell? is it /bin/bash in this case? i think all you have to deal with is a path issue. maybe it's better to install a linux or use a live cd (ubuntu for exampel) and test your scripts in a complete linux/unix environment...

good luck,
DN2

The garbled error message looks like you have DOS line terminators when you should have Unix ones (although I would have imagined Cygwin would be pretty much immune to such issues).

The error message is basically "./pretty/long/path/to/mytest.sh: line 2: (carriage return): command not found", only the carriage return causes the text after it to be printed back at the left margin, overwriting the beginning of the error message.

DOS uses the sequence carriage return + line feed to terminate lines, whereas Unix wants just a line feed.

Blank lines in scripts are not a problem, but see if you can find an editor which allows you to see any control characters, and perhaps remove or replace them.

If ./myscript works for you, then by all means use that. The weird masking which Cygwin has to do to make the file system appear Unix-like is rumored to cause gray hairs. (I never used it much, either.)

Thanks for your replies.

Yes, I do use a winXP os. Maybe I need to run it on real unix system. It seems like there is no a easy way to run it on windows.

Don't be so pessimistic, thousands of people run Cygwin every day, you just need to get used to it and figure out the quirks.

Thanks, era.

I find a way to fix it. Save it in UltraEdit from dos to unix style.

Thank you for your help. I was too pessimistic.

This can also be done in vim by using
Code:
:set ff={dos,unix,mac}
