dot file or configuration files
When setting up a new account on a Linux machine there are many things one can configure. This is a collection of the "dot files", (the ones that usually start with a dot and therefore are hidden) that I use.
alias xssh='ssh -q -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no' alias myscp='scp -q -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no' alias rm='rm -i' alias mv='mv -i' alias cp='cp -i' alias ll='ls -l' alias l='ls -la' export HISTSIZE=1000 export EDITOR=vim
Make bash write to the .bash_history file immediately and read it on every command. Allowing you to search and use the history created in one terminal to be used in another terminal.
Host 10.* 172.31.* 172.32.* 172.33.* 172.34.* StrictHostKeyChecking no UserKnownHostsFile /dev/null
