An AWK-ward problem...

An AWK-ward problem...

[Flint, Paul]

Greetings List lurkers,

I have been troubleshooting some new bash script that I wrote and wanted (for some reason :^) to run on an NT box.

So the struggle began...

Anyway I get the oddest error:

<snip>
/cygdrive/c/Program Files/Git/bin/awk: line 7: $'\r': command not found
/cygdrive/c/Program Files/Git/bin/awk: line 7: $'\r': command not found
warning: LF will be replaced by CRLF in sendjcl.log.
<snap>

So... I check my code and check my code... soon the problem begins to drive me mad...

Then!

I do this from a cygwin ver 2.761 terminal...

$cd /c/cygwin/bin
$dos2unix awk

Now awk works!

The version of Cygwin I am using is 

Thought I would pass this on.

Right.  awk doesn't want CRLF line endings.  Remember that Cygwin is a
linux-like environment.  Linux doesn't always deal well with Windows
line endings either.

I don't believe in this solution:

- The above error messages are not Cygwin gawk error messages.  They
  look like bash error messages.  Bash doesn't understand CRLF line
  endings in scripts unless you explicitly allow that.

- /cygdrive/c/Program Files/Git/bin/awk is apparently the name of a
  shell script.  /cygdrive/c/Program Files/Git/bin/awk is certainly
  not /bin/awk.

- /bin/awk is a symlink to /bin/gawk.exe, an executable.  If you call
  dos2unix on an executable, the executable will be either unchanged,
  or broken with a high probability.

- Even if it doesn't matter in this scenario, Cygwin's gawk understands
  CRLF line endings in awk scripts.

Actually, this looks like you aren’t running cygwin at all.  Did you
install msys git?  That would install a rudimentary set of unix tools
compiled with mingw, the default path is exactly as in your error
message.  Check your path settings.

Current dos2unix skips binary files, unless you force the conversion 
with -f, --force.
