IF condition in shell command line

stepic · 04-23-2009, 01:34 AM

I have some trouble entering if-then condition in a single line on a command prompt.

I am trying this one:

Code:

a="1" ; if [ "$a" = "1"  ]; then echo $a fi

The promt response with a > sign and I don't get the echo.

If I paste the same code into the command line, with enters, it returns the result as expected:

Code:

a="1" ; 
if [ "$a" = "1"  ]; then 
   echo $a 
fi

How could this be done in command line, using one line command?
Thanks.

a="1" ; if [ "$a" = "1" ]; then (hit Enter) echo $a (hitEnter) fi

it does need a character return i guess.

You missed a semi-colon

Code:

a="1"; if [ "$a" = "1" ]; then echo $a; fi

You're absolutely right!
It works now.

Thank you.
