I use something like this - it does a bit of extraneous quoting in some
cases, but it works:
awk '/[^-0-9A-Za-z_.\/:+]/{gsub("\047","&\\\\&&",$0);$0="\047"$0"\047"}1'
Also, see the %q formatter to the internal printf in bash (and ksh93).

That's probably the best route...better to say what's legal than what's
not, since the latter usually only works until you come across
something that should have been on the list ;)

Using the `-exec' option with find may work for your situation. Since
you mentioned bash, perhaps GNU find and GNU xargs are available to you
as well. You may be able to use `-print0' with find and `-0' with xargs
to solve the problem.

Yes, those are all good choices. I guess I was asking if there was a
generalized tool that said "quote this string so it can be used on the
command line". In this case, I have a few thousand files that need to
be moved (one-time) to different directories. There's no way to do it
except by looking at the file list...so I thought to dump the list into
a text file, vi the file to make it into a shell script. Multiple
finds, etc. could also do it...
Anyway, it seems there should be some sort of generalized tool for this
purpose. Alas, I'll have to add it to my list of things to do in my
copious spare time ;)
Thanks! |

If you don't mind some characters being unnecessarily quoted, the
following would do:
find /someplace -print | sed 's,[^/a-zA-Z0-9._-],\\&,g' > /tmp/list
Alternately, a pattern matching special characters could be used but is
messier. Also, I be leaving out something here:
find /someplace -print |
sed 's,[][|&;()<>[:blank:]*?\\'\''"$~!],\\&,g' > /tmp/list
