# less initialization script (csh) # All less.*sh files should have the same semantics! # In case you are curious, the test for non-emptiness is not as easy as in # Bourne shell. This "eval" construct is probably inspired by Stack # Overflow question 13343392. if ( $?LESSOPEN && { eval 'test ! -z "$LESSOPEN"' } ) then : else if ( -x /usr/bin/lesspipe.sh ) then # The '||' here is intentional, see rhbz#1254837. setenv LESSOPEN "||/usr/bin/lesspipe.sh %s" endif endif
