How did you create the shell script file? If you used Windows tools, line-ends are probably marked with carriage-return and line-feed, but bash normally expects just line-feed, and you need to tell it to ignore carriage-return. See IM with Cygwin: Line ends for workarounds.

No change.

That version should be fine.

Does the script always fail, or only with certain inputs? What does "echo $VAR" say?


If I run the script, it fails every time. I've tried a few different images and color numbers, but I always get the same error. If I run "echo $VAR" afterwards, it shows as blank ...

I'm not sure which version I have, it just came bundled with cygwin. Is there a way I can check?

That is odd. Normally, one would put quotes about the hex value xc:'#XXXXXX'. But I think that is not necessary when in the string variable you craated ($VAR), since it worked fine for me. An alternate for xc: is canvas:

The ${1::-4} was just to produce an output filename that was the same as the input filename but with "palette" tagged on to the end. It's not that important to the overall thing, but I get the same error when I remove it.

The $1 and $2 argument values are the filename of the image whose palette I'm ...

I'm trying to make a .sh file for use in cygwin to automate something I find myself doing a lot. The file, test.sh, contains the following:

#!/bin/bash
VAR=$(convert $1 -colors $2 -depth 8 -format "%c" histogram:info: | sort -r -k 1 | head -n 16 | grep -o -E "\#.{0,6}" | sed "s/#/xc:#/g" | sed ':a ...
