ZSH alias with parameter

You can't make an alias with arguments*, it has to be a function. Your function is close, you just need to quote certain arguments instead of the entire commands, and add spaces inside the [].

gitall() {    git add .    if [ "$1" != "" ] # or better, if [ -n "$1" ]    then        git commit -m "$1"    else        git commit -m update    fi    git push}

_{*: Most shells don't allow arguments in aliases, I believe csh and derivatives do, but you shouldn't be using them anyway.}

If you really need to use an alias with a parameter for some reason, you can hack it by embedding a function in your alias and immediately executing it:

alias example='f() { echo Your arg was $1. };f'

I see this approach used a lot in .gitconfig aliases.

I used this function in .zshrc file:

function gitall() {    git add .    if [ "$1" != "" ]    then        git commit -m "$1"    else        git commit -m update # default commit message is `update`    fi # closing statement of if-else block    git push origin HEAD}

Here git push origin HEAD is responsible to push your current branch on remote.

From command prompt run this command: gitall "commit message goes here"

If we just run gitall without any commit message then the commit message will be update as the function said.
