Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Simply sourcing .bashrc does not function correctly when you edit it and change an alias for a function or the other way round with the *same name*.

I therefor use this function. Prior to re-sourcing .bashrc it unsets all aliases and functions.

You can use \n in your inserted data to insert multiple lines.

The leading number is the position in the file where you want the insert, so in this case a '1' indicates the top of the file.

If you have ever been trying to look for a list of processes based on their elapsed time you don't need to look any further.

This command lets you find the list of processes ordered in a reversed order (oldest at the top) that have been running for over an hour on your system. Any system processes are filtered out, leaving only user initiated ones in. I find it extremely useful for debugging and performance analysis.

quickscript () { filename="$1"; history | cut -c 8- | sed -e '/^###/{h;d};H;$!d;x' | sed '$d' > ${filename:?No filename given} }

In order to write bash-scripts, I often do the task manually to see how it works. I type ### at the start of my session.

The function fetches the commands from the last occurrence of '###', excluding the function call. You could prefix this with a here-document to have a proper script-header.

Delete some lines, add a few variables and a loop, and you're ready to go.

This function could probably be much shorter...

Piping a repeated character through the command will result in a single character only if there are more than 4 of them e.g.

echo "aaaaaa bbbbb cccc ddd" | sed -ru 's/(.)\1{4,}/\1/g'

the output will be "a b cccc ddd"

sed -ru 's/(..)\1{2,}/\1/g'

This will remove repeated characters e.g.

echo "xtxtxtxt" | sed -ru 's/(..)\1{2,}/\1/g'

the output will just be "xt"

Pass the files path to finfo(), can be unix path, dos path, relative or absolute. The file is converted into an absolute nix path, then checked to see if it is in-fact a regular/existing file. Then converted into an absolute windows path and sent to "wmic". Then magic, you have windows file details right in the terminal. Uses: cygwin, cygpath, sed, and awk. Needs Windows WMI "wmic.exe" to be operational. The output is corrected for easy...

finfo notepad.exe finfo "C:\windows\system32\notepad.exe" finfo /cygdrive/c/Windows/System32/notepad.exe finfo "/cygdrive/c/Program Files/notepad.exe" finfo ../notepad.exe
