29.10. Fix Quoting in csh Aliases with makealias and quote
For example, here I use makealias to avoid having to quote ! and *:
% makealias mycat cat `ls | sed '1,/!*/d'` | less CTRL-d alias mycat 'cat `ls | sed '\''1,/\!*/d'\''` | less'
I typed the makealias mycat command and the line starting with cat, then pressed CTRL-d and got back an alias definition with all the quoting done correctly.
The properly quoted alias definition is sent to the standard output. That line is what you would use to define the alias.
Here are the quote and makealias aliases themselves:
Go to http://examples.oreilly.com/upt3 for more information on: makealias.csh
alias quote "/bin/sed -e 's/\\!/\\\\\!/g' \\ -e 's/'\\\''/'\\\'\\\\\\\'\\\''/g' \\ -e 's/^/'\''/' -e 's/"\$"/'\''/'" alias makealias "quote | /bin/sed 's/^/alias \!:1 /' \!:2*"
Pretty gross, but they do the job. On Darwin, as on many BSD-derived systems, sed is in /usr/bin, not /bin. You may wish simply to use the command name without the explicit path, or use the explicit (but correct) path. On Linux, the script above does not work with tcsh, which handles multi-line aliases anyway.
