If you ever need to debug a Unix or Linux shell script, you can just add the -x option to the interpreter when you invoke it. You can add the shell's debug option on the command line like this:
sh -x misbehaving_script.sh
or at the end of the first line in your shell script (the she-bang line), like this:
#!/bin/sh -x
I was just working on a shell script related to fonts on a Mac OS X (Unix), system, and when I tried to run it normally, all it gave me was this error message:
$ sh gen_fonts.sh
gen_fonts.sh: line 41: syntax error: unexpected end of file
To help debug the script, I added the -x option, and got the following debug output:
$ sh -x gen_fonts.sh
+ DIR=/Library/Fonts
+ IFS='
'
+ FILE=fonts.html
+ FONTFILE=fonts2
+ echo '<html><head>'
gen_fonts.sh: line 41: syntax error: unexpected end of file
