The BOFH Excuse Server

Display total Kb/Mb/Gb of a folder and each file

How to search for files and open all of them in tabbed vim editor.

Opening several files at once in Vim can be very easy in connection with find command.

View acceptable client certificate CA names asked for during SSL renegotiations

The key is to use the -prexit option at the command line, and then type "quit" instead of CTRL-C to exit OpenSSL. OpenSSL will then dump its last negotiated state, printing out the contents of the renegotiated handshake. Crucial for debugging client certificate configurations on web servers such as IIS, which renegotiate the SSL/TLS connection with the HTTP request in-flight to ask the client for a cert.

Make a playlistfile for mpg321 or other CLI player

Supports other file formats.

Find the package that installed a command

delete file name space

delete file name space the rename is rename perl version

Write a shell script that removes files that contain a string

Deletes files in the current directory or its subdirectories that match "regexp" but handle directories, newlines, spaces, and other funky characters better than the original #13315. Also uses grep's "-q" to be quiet and quit at the first match, making this much faster. No need for awk either.

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" }

print only matched pattern

Print only the matched pattern at the console
