ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^/]*//--/g' -e 's/^/ /' -e 's/-/|/'


I found a command to display directory tree (see above), it didn't work correctly. It gave error message "Illegal variable name". I think the error is at $ sign. How can I modify this command for cshell environment?




variable csh tree

:$ should be in single quotes to stop the shell from expanding it.



so ls -R | grep ':$' | sed -e 's/:$//' -e 's/[^-][^/]*//--/g' -e 's/^/ /' -e 's/-/|/'



Your next thing to learn, is shell quoting, and expansions.



Also a lot of people consider csh to have been a mistake. It is full of odd inconsistent behaviour. Consider another bash, ksh, fish …

    Instead of a shell script you can use an external commands. 'tree' may be available in your environment, then it's easy.



    tree -d
