Useful Aliases in bash

Drop some useful aliases, and a one liner why you use it:

alias 7zadd='7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=64m -ms=on'
Compress with one of the best comp. algos out there + 7z format is platform agnostic.

alias nmcli='nmcli -p -a'
Give me pretty output and ask me if I forgot something.

alias chmod='chmod -c'
Inform me of the change.

Lets see…

# quick blog reading
alias www="lynx -dump"

# just looks better in git diff this way
alias less="less -S --tabs=4"

# die, Python 2, die!
alias python="echo 'Use bpython!' #"
alias python3="echo 'Use bpython!' #"
alias pip="echo 'Use pip3!' #"

# you know, my git log usually looks like: fix, fix, fix, ...
alias commitpush="git commit -am fix ; git push origin HEAD"

Otherwise :

alias ne='emacs -nw'
alias reload='source ~/.bash_profile'
alias clean='rm -rf *~'

Mine are simple yet useful.

alias pc="packer-color --noconfirm"¬
alias ls="ls --color=auto -sh"¬
alias editterm="vim ~/.config/termite/config"¬
alias vpn="cd ~/Documents/VPN && sudo (do vpn stuff, cause OPSEC)"

That’s all I’m using right now. My ls alias is my favourite however.

Nice! I’ve actually found 0x0.st is nice for uploading. You can do most files infact.

Here are my little bash shortcuts!

# a quicker G++
g++50() {
    echo "g++ -std=c++11 -Wall -Werror ${1}.cpp -o $1";
    echo "";
    g++ -std=c++11 -Wall -Werror ${1}.cpp -o ${1}.o;
}

termbin() {
    cat $1 | nc termbin.com 9999
    echo "cat $1 | nc termbin.com 9999"
}

Find the first ten of your most typed commands (good candidates to make an alias).

# Check alias candidates.
function check_ac() {
    history | \
        awk '{CMD[$2]++;count++;}END { for (a in CMD)print CMD[a] " " CMD[a]/count*100 "% " a;}' \
            | grep -v "./" | column -c3 -s " " -t | sort -nr | nl |  head -n10
    }
alias check_alias_candidates='check_ac'

It turns out that my top two commands are ls and clear… probably because I spam them when I’m bored.

Quick suggest - use ^L for clear, so it won’t show up in your hist.

These are the ones I found useful in the last days:

alias getip='curl http://ipinfo.io/ip'
alias proxy='proxychains'
alias proxyip='proxychains curl http://ipinfo.io/ip'

Here’s another one for you ~/Bin/

portsync.sh

#!/bin/bash
host=$1
port=$2
opts=$3
ssh -p 4350 $opts $host -L $port:localhost:$port -N

Usage: portsync.sh hostname port flags
ex. portsync.sh 192.168.1.50 8384 -f

(-f is to fork into background), now you can access port 8384 which has binded to localhost on that server. (useful for services that automatically bind on 127.0.0.1 rather than 0.0.0.0)

192.168.1.50:8384 —> 127.0.0.1:8384
