Computer tips to Jen Gentleman.
For this Twitter thread: https://twitter.com/JenMsft/status/1218526323271823360
I've taken all of these from information I've found publicly available on the interner over the years. I haven't kept all of the sources.
I thought on adding more than bash-related stuff, but I ended up unconvinced. I hope some of this can be useful!
Specifically bash tips. You can put all of these in your ~/.bashrc (unless you have something with that specific name.
It should work in most platforms with bash.
To generate passwords:
pwgen() { < /dev/urandom tr -dc A-Za-z0-9_+-?\?! | head -c$1; }To generate passphrases, install the wamerican package, then use this:
phrase() { shuf -n$1 /usr/share/dict/words | tr '\n' ' '; }# Quick CD
# goto changes directory to the first matching a given string.
# It goes only three levels deep. It also ignores files within node_modules and .git
function goto() {
result=$(find -L . -maxdepth 3 -type d -not -path './node_modules*' -a -not -path '*.git*' | grep ${1})
if [[ -z $result ]]; then return; fi
cd $result
}vim $(git status --porcelain | awk '{print $2}')# gitReport week for one week ago
# gitReport month for one month ago
# gitReport for one day ago
# or like gitReport three months ago
gitReport() {
if [ "$1" = "week" ]; then
since="one week ago"
elif [ "$1" = "month" ]; then
since="one month ago"
elif [ "$1" = "" ]; then
since="one day ago"
else
since=$@
fi
pad=$(printf '%0.1s' " "{1..60})

echo -e "\n\e[37;1mChanges from $since:\e[0m"

if [ "$commits" != '' ]; then
printf '%s' "$author"
