If the original title begins with a number or number + gratuitous adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys." Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."
Here is one that should reset your terminal after accidentally reading a binary file, in most cases. Some of these are different on linux vs. unix vs. mac. You could put these in a file in /etc/profile.d/ or in your ~/.bashrc
alias fix='reset; stty sane; tput rs1; clear; echo -e "\033c"'
List only directories:
alias lsd='ls -h -b --color=auto -d */'
List by size:
alias lss='ls -Ao --sort=s'
Hand dyslexia, or the alternate to installing "sl"
alias sl=ls
alias xit=exit
alias moer="more"
alias mroe="more"
Long PS
alias p="ps -Hefcwww"
Shorthand for disk and memory usage:
alias f="df -Ph;free -m"
Bash function to display colors:
function colors()
{
for fgbg in 38 48 ; do
for color in {0..256} ; do
echo -en "\e[${fgbg};5;${color}m ${color}\t\e[0m"
if [ $((($color + 1) % 10)) == 0 ] ; then
echo
fi
done
echo
done
}
Functions to do rot13 and rot47 to get around word filters
function rot13() { if [ -r $1 ]; then cat $1 | tr '[N-ZA-Mn-za-m5-90-4]' '[A-Za-z0-9]'; else echo $* | tr '[N-ZA-Mn-za-m5-90-4]' '[A-Za-z0-9]'; fi }
function rot47() { if [ -r $1 ]; then cat $1 | tr '\!-~' 'P-~\!-O' ; else echo $* | tr '\!-~' 'P-~\!-O'; fi }
A couple of memory stat functions
function memfree() {
free|awk '/^Mem/ {printf "%4.1f",($2-$4-$6-$7)/$2*100}'
}
function memperuser() {
ps aux | awk 'NR != 1 {x[$1] += $4} END{ for(z in x) {print z, x[z]"%"}}'
}
These are pretty neat, but weirdly uninformed on some things
.
If you're using GNU tar the alias should just be "tar -xvf" since it can autodetect compression (though I'm not sure if that's suffix-based or file type). This also means you can append your own -j or whatever for different compression types if you need to do so manually.
Specifying "wget -c" does not mean you'll be able to resume if something goes wrong, it forces resumption from a partial file you already have on a subsequent invocation. The reason to specify it on the first invocation is just so that you can be lazy and reuse that command line.
The shasum command is from Perl on most (all?) platforms, sha256sum from GNU coreutils or equivalent may be needed if it's missing and may have higher performance.
Probably most importantly, ipconfig is OS and distro-specific. It was missing on the first linux systems I checked (Ubuntu and openSUSE). It's useful, but it's a bit like listing a launchctl alias without specifying it's largely macOS-specific.
> A normal ping will go on forever. We don't want that. Instead, let's limit that to just five pings.
It almost always what I want.
> alias getpass="openssl rand -base64 20"
If you really want to be handy, use "pass generate -c" instead of openssl, you got the password stored in your passstore and temporary copied to the clipboard.
On Mac ⌘ + k works well in iTerm and the stock terminal. I can't be sure if it is a standard thing or not so I'm not going to make any assumptions about it working in other places.
