I wanted to set an alias for a find command containing the -regex
switch. For simplicity I will use this example:
find . -type f -regex '.*\.txt$'
This expression simply gives a list of all *.txt files in any directory under the current path.
The above command works fine when running in the terminal, but when
saving that to a tcsh alias, that $ needs to be escaped:
alias findtxt "find . -type f -regex '.*txt'\"\$"''"
A simple
$has to be written as'\"\$"'!!!
Granted that I will usually get the same result if I did alias findtxt "find . -type f -regex '.*txt'" instead. But this turned out
to be an interesting exercise on how to escape a $.
