Re: perl callable from bash?

Maybe your scripts (firstscript and secondscript) have <CR><LF> line terminations instead of the usual (on unix) <LF> line termination. That might explain the first of your error messages. The second error message, beginning without an opening single quote and with the text ".links" is a bit more puzzling.

One way to see what your line terminations are is to use the "od" command. For example, in the following, each line ends with "\r\n".

$ od -c test.html
0000000   <   h   t   m   l   >  \r  \n   <   h   e   a   d   >  \r  \
+n
0000020   <   t   i   t   l   e   >   t   e   s   t   <   /   t   i   
+t
0000040   l   e   >  \r  \n   <   /   h   e   a   d   >  \r  \n   <   
+b
0000060   o   d   y   >  \r  \n   T   h   i   s       i   s       s   
+o
0000100   m   e       "   t   e   x   t   "       i   n       t   h   
+e
0000120       b   o   d   y   .  \r  \n   <   /   b   o   d   y   >  \
+r
0000140  \n   <   /   h   t   m   l   >  \r  \n
0000152

After converting the line endings, it appears as follows:

$ od -c test.html
0000000   <   h   t   m   l   >  \n   <   h   e   a   d   >  \n   <   
+t
0000020   i   t   l   e   >   t   e   s   t   <   /   t   i   t   l   
+e
0000040   >  \n   <   /   h   e   a   d   >  \n   <   b   o   d   y   
+>
0000060  \n   T   h   i   s       i   s       s   o   m   e       "   
+t
0000100   e   x   t   "       i   n       t   h   e       b   o   d   
+y
0000120   .  \n   <   /   b   o   d   y   >  \n   <   /   h   t   m   
+l
0000140   >  \n
0000142

Now the lines end with "\n" only.

Depending on your unix installation, you may have a command "dos2unix". I used the vim editor. You might also be able to use the "tr" command as "tr -d '\r' <file.old >file.new"

How did you create your perl script files?

Normally I'd use Emacs, but since the target is down I'm using EditPlus2 which can switch hit. Also using Cygwin to emulate the real environment. Don't think I mentioned it, but both scripts run fine from the command line. Just not in the shell script.
