Subject: cygwin-bash compat/regression bug... startup line prob
Date: Mon, 28 Apr 2014 20:43:00 -0000 [thread overview]
Message-ID: <535EBD61.5080109@tlinx.org> (raw)
This 'used' to work...but doesn't now: -- running
bash with the "-u" flag:
> t.sh
/usr/bin/bash: - : invalid option
Usage: /usr/bin/bash [GNU long option] [option] ...
/usr/bin/bash [GNU long option] [option] script-file ...
GNU long options:
--debug
--debugger
--dump-po-strings
--dump-strings
--help
--init-file
--login
--noediting
--noprofile
--norc
--posix
--protected
--rcfile
--restricted
--verbose
--version
--wordexp
Shell options:
-irsD or -c command or -O shopt_option (invocation only)
-abefhkmnptuvxBCHP or -o option
> which t.sh
/Users/law.Bliss/bin/t.sh
> cat bin/t.sh
#!/bin/bash -u -x
echo "Hello World"
>
-----------------------------
It has something to do with the "-u" switch -- the "-x" was
added to try to figure out why a script that had just
#!/bin/bash -u
died w/o executing a single line.
If I run it via:
> bash t.sh
Hello World
>
---works---
Also weird -- the interp line says "/bin/bash" not "/usr/bin/bash"
as the shell, so why does the error come from /usr/bin/bash?
It doesn't when I do it interactively:
> /bin/bash - -
/bin/bash: -: No such file or directory
---
or 'bash' alone:
> bash - -
bash: -: No such file or directory
----
Ideas? would a cygcheck be of any use?
Note, if I combine the switches (-ux), it works -- but I only
added the '-x' to debug why '-u' didn't work.
> uname -a

This, also, doesn't work:
> echo t.sh|bash -i #(with or without '-i')
#note -- first some unrelated output from confused startup scripts:

## here is the 'echo' being read into bash:
law.Bliss> t.sh

/usr/bin/bash [GNU long option] [option] script-file ...
