df without line wrap on long FS name

Personally I think line wrap in default df command is annoying for scripting & seeing. So I overwrite it. Maybe more work should be done if wrapped line is over 2... Show Sample Output

Post to twitter via curl, Windows version

Aside from curl one will need iconv windows binary since windows lacks a native utf-8 cli interface. In my case I need a proxy in China and iconv to convert gbk status string into utf-8. GnuWin32 is a good choice with loads of coreutils natively ported to Windows "FOR /f" is the solution to pass iconv output to curl.

Check These Out

Renaming a file without overwiting an existing file name

Sometimes in a hurry you may move or copy a file using an already existent file name. If you aliased the cp and mv command with the -i option you are prompted for a confirmation before overwriting but if your aliases aren't there you will loose the target file! The -b option will force the mv command to check if the destination file already exists and if it is already there a backup copy with an ending ~ is created.

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"

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" }

get you public ip address

Group OR'd commands where you expect only one to work

Something to stuff in an alias when you are working in multiple environments. The double-pipe OR will fall through until one of the commands succeeds, and the rest won't be executed. Any STDERR will fall out, but the STDOUT from the correct command will bubble out of the parenthesis to the less command, or some other command you specify.

Figure out what shell you're running

Stop Flash from tracking everything you do.

Brute force way to block all LSO cookies on a Linux system with the non-free Flash browser plugin. Works just fine for my needs. Enjoy.

Generate list of words and their frequencies in a text file.

To create files with specific permission:

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"
