Returns the most recently modified file in the current (or specified) directory. You can also get the oldest file, via: ls -t1 $* | tail-1 ;
ls -al gives all files, sort +4n sorts by 5th field numerically
Find and delete files over 15 days Show Sample Output
There's other expansions as well such as `{one,two,three}'. Check the curl docs for more.
This is a slight variation of an existing submission, but uses regular expression to look for files instead. This makes it vastly more versatile, and one can easily verify the files to be kept by running ls | egrep "[REGULAR EXPRESSION]"
urls.txt should have a fully qualified url on each line
prefix with
rm log.txt;
to clear the log
change curl command to
curl --head $file | head -1 >> log.txt
to just get the http status

Some shell newbies don't know this very handy file management related command so I decided to include it here. You need to have the "file" package installed. Show Sample Output
Ever wanted to find the most recently modified files, but couldn't remember exactly where they were in a project directory with many subdirectories? The "find" command, using a combination of "-mtime -N" and "-depth -D" can be used to find those files. If your directory structure isn't very deep, just omit the "-depth -D", but if your directory structure is very deep, then you can limit the depth of the traversal using "-depth -D", where "D" is the maximum number of directory levels to descend.

Many Mac OS X programs, especially those in Microsoft:Office, create ASCII files with lines terminated by CRs (carriage returns). Most Unix programs expect lines separated by NLs (newlines). This little command makes it trivial to convert them. Show Sample Output
Finds files modified today since 00:00, removes ugly dotslash characters in front of every filename, and sorts them. *EDITED* with the advices coming from flatcap (thanks!)
