Title
Body
I'm currently having problems to execute a command from a shell variable. In general the following works as expected: COMMAND="echo A" echo $COMMAND $COMMAND produces: echo A A But if I do COMMAND="su aUser -s /bin/bash -c 'echo A'" echo $COMMAND $COMMAND I get su aUser -s /bin/bash -c 'echo A' Password: A': -c: line 0: unexpected EOF while looking for matching `'' A': -c: line 1: syntax error: unexpected end of file If I enter the line su aUser -s /bin/bash -c 'echo A' directly it works as expected. It seems my assumption that $COMMAND is equal to entering the content as command directly is wrong. Questions 1) Does anyone know how I can run the command from a variable? 2) What exactly is the difference between COMMAND="command" $COMMAND and command ?
