This is not specific to tcsh's printexitvalue=1. This bug happens if the tcsh's startup scripts create any output. Test Case: 1. Create /etc/profile.d/test.csh that contains: --- #!/bin/tcsh echo "FOO" --- 2. Login as a user with tcsh as the default shell 3. Run: less /etc/hosts Results: You see the word "FOO" displayed rather than the text of /etc/hosts Cause: less does a popen("/bin/tcsh -c /usr/bin/lesspipe.sh /etc/hosts") where the shell is gotten from the users default shell.
