calling a cl command from within a C-shell script

RhEvans41 wrote on May 28, 2008

I have a shell script which creates a file which I then try to get IRAF to
execute. The script used to work fine, but I have not used it in over 12
months and now I find it does not work. I am running Version 2.14 on a
Mac.

The relevant part of the script is the following

--------

#Create iraf script to check status of keyword "reduce", which will
#exist and have a value of 1 if the files have already been run
#through this script
rm -f /tmp/reducestatus$$

cat > /tmp/cl.reduce$$ << EOF
#
cd $current
hselect @objectlist "\$I,reduce" yes > /tmp/reducestatus$$
logout

.
wq
EOF

#Now run this script
cd $irafdir
cl < /tmp/cl.reduce$$ > /tmp/cl.logreduce$$

-----

Whereas before the file /tmp/reducestatus$$ would be created, it is now
not creating it. The cl.logreduce$$ file is not very informative, all it
has in it is

>cat cl.logreduce
setting terminal type to xgterm...

Unfortunately I am stumped as to what is going on.... Any ideas what part
is now not working?

In v2.14 we switched to the ECL as the default, this uses the readline interface to permit the history editing and fix the backspace problem, but has a side-effect with host scripts such as this. Specifically, if the current directory contain a login.cl file the 'stty xgterm' command is causing the problem.

Try running the script *without* a login.cl file in the current directory, or to get the old CL execute using

% cl -old < /tmp/cl.reduce$$ > /tmp/cl.logreduce$$

Otherwise, I wouldn't expect your script to work since the '@objectlist' would require a CL variable 'objectlist' to be present. Since you say 'relevant part of the script' I'll assume for now this is set elsewhere. Anyway, hope this helps.

Cheers,
