Check These Out

Get information about libraries currently installed on a system.
This command is very helpful when we need to duplicate a test scenario and first we want to find out the installed libraries together with the version and release numbers and architecture. (look example) Command can be tuned by choosing just the names of libraries we are interested in. For example glibc and gcc.

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" }

Congratulations on new year
Requires installed command line PHP. Also, try at different dimensions of terminal window

Display network pc "name" and "workgroup"
Checks for PC samba name and workgroup. Works fine for Windows hosts and Linux/UNIX PCs running Samba.

Display standard information about device
Queries the specified ethernet device for associated driver information

Draw kernel module dependancy graph.
parse `lsmod' output and pass to `dot' drawing utility then finally pass it to an image viewer

Rename files in batch

Find all dotfiles and dirs
find makes it easier, filtering . and .. maxdepth could be removed, finding entries recursively. Removing mindepth causes . to appear

Disconnect telnet
You are stuck with testing a tcp port using telnet, and must kill the telnet session from another terminal... Or, press ctrl+5 and write close/quit to force the current connection to close..

Edit all files found having a specific string found by grep
The grep switches eliminate the need for awk and sed. Modifying vim with -p will show all files in separate tabs, -o in separate vim windows. Just wish it didn't hose my terminal once I exit vim!!
