this is probably a dumb problem but here goes...
just for the hell of it, i want my .bash_profile to tell me what host i'm
connecting from when i log in. so i have some lines that look like this:
if $SSH2_CLIENT
then
MYHOST=`echo $SSH2_CLIENT | match_ip.pl | hostlookup.pl`
echo Connecting from ${MYHOST}...
fi
where match_ip.pl is a perl script that reads a line from STDIN and prints
the first string that looks like an IP address to STDOUT, and
hostlookup.pl is a perl script that reads a line from STDIN, does a name
lookup on that line, and prints the name to STDOUT.
when i log in, i get an error similar to this:
bash: 216.141.188.121: command not found
it looks like bash takes the output of matchip.pl (the IP) and treats it
as a command to be run, when i just want it to be passed to the STDIN of
hostlookup.pl.
now, if i try the following from a command line:
MYVAR=`echo $SSH2_CLIENT | match_ip.pl | hostlookup.pl`
echo $MYVAR
i will get the results i want, so i know that my perl scripts are okay.
what am i doing wrong in my .bash_profile?
thanks in advance,
jacob
