Syntax error when trying to pipe multiple commands in an alias definition

Hey can anyone help me to solve syntax error on creation of alias.I am new to bash so i am not aware of any restriction in use of alias command

Every time i run this alias command

alias user='responseVar=$(curl -XGET link)  && echo ${responseVar} | jq '.offsets[] | " (.topic) (.offset) (.logSize) "' | awk 'NR>1{arr[$2]=arr[$2]+($4-$3)} END{for (a in arr) print a"="arr[a]}''

I get this error.

bash: syntax error near unexpected token `('

Answer

Avoid using alias (they’re only allowed in interactive shells) and define a simple function instead to do

doSomething() {
    curl -XGET link | jq '.offsets[] | " (.topic) (.offset) (.logSize) "' |
       awk 'NR>1{arr[$2]=arr[$2]+($4-$3)} END{for (a in arr) print a"="arr[a]}'
} 

and defined in any of your startup configuration files(e.g. .bashrc for instance) and launch and new shell and do just

doSomething
