Get rid of the single quotes. They prevent variable expansion.

sed "/AXG/s/;/${HOMEx}/g"

If HOMEx="test" this becomes: sed "/AXG/s/;/test/g"

Compare https://www.gnu.org/software/bash/manual/html_node/Double-Quotes.htm and https://www.gnu.org/software/bash/manual/html_node/Single-Quotes.html

Beware though: if the variable HOMEx contains something sed recognises you'll get an error. In this case the main things would be a backreference like "\1" or forward slash "/".

  • this give a error unknow character – victorhernandezzero Mar 28 '17 at 1:45
  • Be careful about what's in the variable though. If it contains something sed recognises you'll have problems – squashed Mar 28 '17 at 1:50
