How to concat variable and string in bash script

bash shell scripting concatenation concat

Strings are concatenated by default in the shell.

value="$variable"text"$other_variable"

It's generally considered good practice to wrap variable expansions in double quotes.

You can also do this:

value="${variable}text${other_variable}"

The curly braces are useful when dealing with a mixture of variable names and strings.

Note that there should be no spaces around the = in an assignment.

Mac OS X 10.12 works with following ...

#!/bin/bashvar1=barvar2=foovar3="$var1"sometextecho $var3

Result

= barfoosometext

Late for the party, my 2 cents for another solu., also works in zsh:

i=`date +%d%b`

val1="$i-i-*"
