Hi Guys,

IF i have to append data to a variable, i simply use the following. What can i do to append data to the beginning?

 
  VAR+="data"

try

var="Makarand"
var=$var"Dodmise"
$ echo $var
MakarandDodmise

Hello,

This should add text to beginning of the variable.

VAR="data" $VAR

Cheers!

That will not work. Remove the space, and, to be sure, double-quote $VAR:

VAR="data""$VAR"

Just to add a comment to these solutions, as variables get expanded inside double quotes, I would have thought only one pair of double quotes is required to enclose both the variable itself as well as the additional data:

VAR="data${VAR}"

My Bad, Typo..

try

akshay@nio:~/tmp$ variable="abc"
akshay@nio:~/tmp$ printf -v variable "%s%s" def $variable
akshay@nio:~/tmp$ echo $variable
defabc
