I would like to define an expression for find which includes a wildcard in a -name subexpression:
find_expression="-type f -name *.csv -mtime +14"
And then use it in a couple of places later on:
find /var/data $find_expression -delete -print
If i don't quote the use of
$find_expression, then when the variable is expanded, the glob is resolved, and if there happens to be a CSV file in the current directory, that find command is going to do the wrong thing.
If i do quote the use of
$find_expression, then when the variable expanded, it is not split into multiple arguments to find, and the find command does the wrong thing.
This doesn't help:
find_expression="-type f -name '*.csv' -mtime +14"
I believe because it results in a fourth argument which actually starts and ends with single quote characters.
I could surround the invocation of find with a
set -f /
set +f pair. However, that means i couldn't then use a glob for the paths given to the find expression, so it's not a general solution.
Perhaps i could use an array here.
But is there any way to specifically expand a string into arguments without resolving globs?
