Checks apache's access_log file, strips the search queries and shoves them up your e-mail

It's not a big line, and it *may not* work for everybody, I guess it depends on the detail of access_log configuration in your httpd.conf. I use it as a prerotate command for logrotate in httpd section so it executes before access_log rotation, everyday at midnight.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

quickly rename a file

Check apache config syntax and restart or edit the file

Checks the apache configuration syntax, if is OK then restart the service otherwise opens the configuration file with VIM on the line where the configuration fails.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Pretty man pages under X

You're a developer - but it doesn't mean you have to slum it! Why not spice up your man page lookups by using a decent PDF viewer. I use 'xpdf' - maybe you prefer acroread, whatever, it's just as fast as plain dull ASCII on today's machines and you can still search for stuff - that's the main reason I use PDF and not PS.

Show every subdirectory (zsh)

Calculate days on which Friday the 13th occurs

Alter the years in the first brace expansion to select your year range. Modify date format to your liking but leave " %w" at the end.

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Copy a directory recursively without data/files

Display all shell functions set in the current shell environment

Uses the shell builtin `declare` with the '-f' flag to output only functions to grep out only the function names. You can use it as an alias or function like so: alias shfunctions="builtin declare -f | command grep --color=never -E '^[a-zA-Z_]+\ '" shfunctions () { builtin declare -f | command grep --color=never -E '^[a-zA-Z_]+\ '; }
