Uses bin/sh to run bash script (not valid on ubuntu)

[jwadamson]

Ubuntu has a highperformance posix dash for its /bin/sh. This means that vimcat does not work on ubuntu.
vimcat uses #!/bin/sh but explicitly states in the header comment that it is a bash script. This is incorrect behavoir. I would expect that the script should either be updated to avoid any non-posix functionality or more likely the interpreter line should be changed to /bin/bash so that it uses the interpreter it expects.

Thanks for the report, I'll look into it.

I try not to rely on bash so that the scripts work on systems like solaris and the bsds, so I'll probably rewrite it in bourne.

I now see in history that vimcat is an experimental utility. It caught my eye so I tried to run it to figure out what it was for, and it failed due to the bashism. Thanks for the prompt response.

I haven't had a chance to rewrite the script in bourne shell, but in the meanwhile I've changed the shebang from #!/bin/sh to #!/bin/bash and uploaded it to vim.org:

There is now shell detection code that tries to find a POSIX shell on all systems, while remaining a #!/bin/sh script.
