Hi, I have a csh script in which I'd like to do set up a list of vars
and then to chk each of these are set, something like the below.
However, I can't find the magic incantation that allows to to check
${$Vars} eg if $InMetFiles is set on the first loop - suggestions
welcome!
#!/bin/csh
foreach Vars (InMetFiles InTerFile OutDir)
echo Checking $Vars\.\.\.
if ( ${?Vars} == 0) then
echo $Vars not set \- aborting
exit 1
endif
end
maybe use "" (empty string) instead of 0 in the comparison.
