That means you are running tcsh (T shell) and it's your default shell is tcsh. I just wanted to confirm your putting the path edits in .cshrc was correct
since you wrote here:
I install cadence EDA tools in my F26 laptop
after setting up the .cshrc with the paths and I could tell that the command is there by using which
which implies you use csh or tcsh as only csh or tsch use .cshrc,
This guy Andrew Beckett
seems to say you need these on the path:
"You need to have <IC61instDir>/tools/bin and <IC61instDir>/tools/dfII/bin in your UNIX path."
I also found a thread on an forum:
(see post 63)
that imply that Cadence depends on many environment variables in the users
alias lmli='/home/frax/edatools/virtuoso/tools/bin/lmgrd -c /home/frax/edatools/virtuoso/share/license/license.dat'
NOTE those are all in bash format, for csh/tcsh have to use "setenv OA_HOME /home/frax/edatools/virtuoso/oa_v22.41.029" using the threads
value as an example.
