COMPARING STRING VALUES TO A VARIABLE and return code dignostics
Hey Folks and Gurus there
I am trying to replicate this logic in bash :



(1) if [ "$var" = Uppercase (this value list e.g."t1",'t2") ] ; then
function1 parameters &
function2 parameters &
fi

Is there an easy method esp one with regex that can do this comparision.
e.g. $var is compared to this list ( case regardless ) ( 'foo','foobar','cheese burger' )

(2) how can I express precedence of operation in an if statement .
e.g.
if [ ( expression1 -a expression2 -o expression3 ) -o (expression4 -a expression5) ]
well how do I convey this . Round brackets are not allowed.

(3) Finally if I have a situation. where I am calling a function in a function :

f1()
{ blan }

f2()
{blah
Conditional logic here
f1 variable & # St1
f1 variable & # St2

}

main flow statement
I want to check when St1 and St2 both have completed and when that happens ( whenever. Remember they run in parallel - with an & )
I want to shell to do something.
How should I replicate this logic .
Thanks in advance .
Bye
Sam

#1:
echo $var | egrep -i "value1|value2|value3"

#2: parens ARE allowed. You simply must escape them with a backslash. ie, \( 1 = 2 \) -a \( 1 = 3 \)

#3: You can either wait for each job or wait for all tasks to complete. The second form is simply:
Code:
job1 &
job2 &
wait
