AWKPATH question

I have set enviroment AWKPATH in ~/.bash_profile including ~/lib/awk
which contains some function
at command line using, there's no problem.
fang@bash ~
$ uname -a
CYGWIN_NT-5.1 bash 1.5.25(0.156/4/2) 2008-03-05 19:27 i686 Cygwin

fang@bash ~
$ echo $AWKPATH
/usr/lib/awk:/home/fang/lib/awk

fang@bash ~
$ echo abcd |awk -f reverse.awk  --source '{print reverse($0)}'
dcba

put in a file ,I get an error

fang@bash ~
$ cat junk
#! /bin/gawk -f reverse.awk --source

{
print reverse($0)
}

fang@bash ~
$ echo abcd |./junk
gawk: fatal: can't open source file ` reverse.awk --source ' for
reading (No such file or directory)

calling gawk from shell, there's no problem

$ cat junk2
#! /bin/bash

gawk -f reverse.awk --source '{print reverse($0)}'

fang@bash ~
$ echo abcd | ./junk2
dcba

how to solve the problem, thanks

You probably haven't exported AWKPATH. This is more of an OS-specific issue 
and
so is OT here so follow up at comp.unix.shell if that's not it.

Looks like gawk is receiving the filename as "reverse.awk --source" instead
of reverse.awk. comp.unix.shell is more appropriate.

I have export enviroment var in bash_profile

fang@bash ~
$ cat .bash_profile | tail -n6
export NNTPSERVER='freenews.netfront.net'
export LYNX_CFG="$HOME/lynx.cfg"
export LESSCHARSET=latin1
#export LC_CTYPE=zh_CN.gbk
export CHARSET=GBK
export AWKPATH="/usr/lib/awk:$HOME/lib/awk"

fang@bash ~
$ pwd
/home/fang

fang@bash ~
$ unset AWKPATH

fang@bash ~
$ echo $AWKPATH


fang@bash ~
$ source .bash_profile

fang@bash ~
$ echo $AWKPATH
/usr/lib/awk:/home/fang/lib/awk

fang@bash ~
$ pwd
/home/fang

fang@bash ~
$

fang@bash ~
$ echo abcd | gawk -f reverse.awk --source '{print reverse($0)}'
dcba

fang@bash ~
$ cat junk
#! /bin/gawk -f reverse.awk --source
{
print reverse($0)
}

fang@bash ~
$ echo abcd | ./junk
gawk: fatal: can't open source file ` reverse.awk --source' for
reading (No such file or directory)

fang@bash ~
$

any ideas? thanks

As I said, if that isn't the problem, follow up at comp.unix.shell.

in many flavors of UNIX like the Linux emulation CYGWIN the shebang line
can only have one argument (option) and must be shorter than 32 bytes.
Therefore your shebang approach doesn't work.

Try:

------------------8<-------------------------------
#!/bin/igawk -f
@include reverse.awk
{
print reverse($0)
}
------------------8<-------------------------------

Perhaps you have to fix the igawk path in the shebang line.

Look at:

which(1)
igawk(1)

Are you sure about the size of the limit? I agree there is a limit but I
thought it was more than 32 bytes. I know it is for the linux (suse) I
have handy and I just tried cygwin with this:

try.sh
#! /home/smoore/ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
/bash.exe
echo "hello"

With no problems.
