Functions are great. Aliases are no replacement for them since every time you'd use one, the arguments are likely to be different. Here are a few examples I use for WSL: pbpaste () { powershell.exe -noprofile -command Get-Clipboard } pbcopy () { clip.exe < "${1:-/dev/stdin}" } yt () { youtube-dl -fmp4 --no-check-certificate `pbpaste` } None of these would work as aliases, unless you only want them to keep doing whatever they did in the first invocation every time thereafter. Eg: as an alias, yt would be limited to downloading the same video over and over again.
