    Triggers in iTerm – Watching For Specific Strings

    I was recently performing a git-add in patch mode (  git add -p ) as I normally do, and realized there were a few lines I needed to make sure I didn’t commit. These lines were sandwiched between other lines that I did want to commit, and there were hundreds of changes, so it was hard to spot them. I wondered if iTerm2 had a way of highlighting or alerting when a specific word shows up in the terminal. To my surprise I found a “Triggers” section under the “Profiles » Advanced” tab in the settings for the app. iTerm2 really can do everything!

    Customizable Date variables in Keyboard Maestro

    UPDATE: Though the solution below works well, I do recommend following the first commenter’s advice and using the ICUDateTime text tokens instead, which allow you to use any ICU date format, without having to invoke a shell script.

    Sometimes you need a date and/or time variable in your Keyboard Maestro macros. The easiest One way I’ve found to do this is via an “Execute Shell Script” action. You’ll just use the date command and format as desired.

    Determining Your Most Used Commands in Terminal

    I’m always looking to automate things using Alfred, Keyboard Maestro, Text Expander, and Python. I was curious which terminal commands I use most often, so I did some experimenting. Basically I wanted to know how many times I’ve executed each unique command ( ssh myserverx or ssh myservery, not just ssh). I started by piping the output of history to  sort (to group), then to  uniq (to count), then back to sort (to sort by the number of occurrences).

    Unfortunately, the result contained the same number of lines as the original history output. I figured this was because each line had a unique integer prefix (the line number in the history output). As it turns out, ~/.bash_history (where history gets its records) doesn’t contain line numbers. I simply changed the source and it worked like a charm:

    “755”-style permissions with ‘ls’

    After a quick Google search for “ls permissions octal” I found a very handy alias to put in my .bashrc. Not only is it handy to see the OCTAL value of the permissions for each file/dir, it will undoubtedly help you more quickly recognize/interpret the normal ls -al output.

     Example usage:
    You can also type (or paste) this slightly different version into terminal:

    Automatically Stage All Deleted Files (Git)

    Tab-completion is a really nice thing that we often take for granted. While working with Git I’ve found that it becomes inconvenient to stage (add for inclusion in the next commit) removed files using git rm path/to/my/file.php. Tab completion doesn’t work on paths that no longer exist, so you have to manually type the path to the deleted item. The following snippet automatically stages ALL removed files.

    git ls-files -d -z | xargs -0 git rm --cached --quiet

    Automatically Change Links from Absolute to Relative

    In this example I’m showing one way to quickly convert all a href and img src paths from absolute to relative. It’s quite a time saver, but I suggest committing your latest changes before trying anything here! If you aren’t using a version control system, make a backup somewhere… please! Note: Both of these commands are one-liners.

    In the examples/results below, I tried to target most situations. You should see subtle differences between each example.
