Variable parse

Leo The Cat — Tue, 21 Dec 2010 15:38:54 GMT

Hi

I have this incoming for a grep command.
AAA=1
BBB=1
CCC=2
DDD=533
EEE=991

Question: How to exploit the parse to call a function with the value after the '=' operator.
func(1)
func(1)
func(2)
func(553)
func(991)
...

Bests Regards
Den

Hi Den:

Why not something like:

# awk -F= '{system("echo "$2)}' file

...where 'echo' is your function.

Regards!

Hi James

It's because my function is in my ksh

function testentry {

echo "in"
echo $1
...
}

awk -FSERVICE= '{system("testentry "$2)}' /su02/automationlogs/009/odb_SrvLoop_RetrieveServiceNames.log

The run has errors like this:

Global TnsNames.ora check

Check is running from stha2a034

Hi (again) Den:

> t's because my function is in my ksh

OK, consider something like this:

# cat ./myparse
!/bin/sh
MYINPUT=$@
function MYFUNC
{
echo "I see $@"
}
for VAR in ${MYINPUT}
do
VAL=$(echo ${VAR} | cut -d"=" -f2)
MYFUNC ${VAL}
done

...

You could do:

# ./myparse a=1 b=2 c=3

# ./myparse $(< inputfile)

# ./myparse $(grep "=" inputfile)

Regards!
