I have a feeling that tclsh (TcL shell) in cygwin cannot follow
symlinks when using exec or other methods of calling programs.
I am using a tclsh script that calls zcat, which is really a symlink to gzip.

The script that follows gives "zcat: command not found":

#!/bin/tclsh
exec zcat test.gz >test.txt   #(It cannot follow the symlink?!)

But if I get rid of the symlink by changing the name of gzip.exe to
zcat.exe and copy it over zcat.exe in /bin, the script unzips test.gz
with no problems.

#!/bin/tclsh
exec zcat test.gz >test.txt #works when I copy gzip.exe binary over
zcat.exe symlink


On the other hand, the perl script, for example, has no problem with
this, so I think it has something to do with TcL.
#!/bin/perl
print `zcat test.gz >test.txt`   #works OK

Has anyone encountered this problem?

Thanks

  J. Stevens
