tail -f filename should definitely make the list, essential for watching what's appended to log files in real time.
I prefer:- tail -F filename as most of the logfiles I need to watch tend to wrap at some point and 'tail -f' doesn't check for inode changes. (-F is a non-standard option, it's there on GNU's [EDIT] tail binary and OS-X but not Solaris for example).
I was expecting to see the first comment in here complaining about his use of 'cat', as in all of the examples his second argument could've easily taken a filename argument.. sort order.* is surely more elegant than cat order.* | sort which is fair enough, however, as it happens, i generally do end up using 'cat' in the way he's used it.. for such small jobs nobody can be genuinely worried about the overhead, and it…

grep Hardcover | grep KindleI thought to learn something useful for programing (debugging, program runtime analysis, etc.). But instead the article is just about the generic commands cat, sort, grep, cut, sed, uniq, find and less. It is not really development related.

I have found it to be surprisingly useful. Nobody uses all the commands but remembering that something like zcat exists can be extremely useful. Also remembering to pipe through sort before sending through uniq is helpful as well.

I end up sending to a file, chmod, then run it at the shell.
how do I execute the out put of something like this: grep -i 'pattern' file | awk '{print $5}' | sed 's/^/cmd/g' I end up sending to a file, chmod, then run it at the shell.
