awk: string too long near line 1
awk: syntax error near line 1
awk: illegal statement near line 1

Any idea how to accumulate all of the string in variable A?

What do you want to check in that if condition ?

I'm reading between the lines, but do you want to put the group members into a variable based on the group name and group ID?

i.e.

A=$(awk -F: '$1$3 == "tech111" {print $NF}')

If not then how many servers do you have where exactly this number of members were added to that group in exactly that order?

i'll reframe my problem...this should be easy to debug ...

bash-3.00$ A=`cat /etc/group|awk -F: '{if ($1$3 == "secur138"){print $NF}}'|sort|uniq`
bash-3.00$ echo $A
t9330sp,t0096pg,t6899bs,t2483eb,t1563dr,t6658pb t9330sp,t0096pg,t6899bs,t2483eb,t1563dr,t6658pb,smadmn,sysweb,root

See that green colored string....rest all strings(or members) are comma separated....whereas this string is not..it should have been t6658pb,t9330sp...

and its happening because

bash-3.00$  cat /etc/group|awk -F: '{if ($1$3 == "secur138"){print $NF}}'
t9330sp,t0096pg,t6899bs,t2483eb,t1563dr,t6658pb
t9330sp,t0096pg,t6899bs,t2483eb,t1563dr,t6658pb,smadmn,sysweb,root

i have two groups defined with same name and id ,but few diffrent members....

My code looks like following to capture these comma separated strings:

Host etcGroup DUP:

cat /etc/group | awk -F':' '{print $1$3}'|sort|uniq


Userlist:

A=`cat /etc/group|awk -F: '{if ($1$3 == "@@Host etcGroup.DUP@@") {print $NF}}'|sort|uniq`

B=`echo $A|wc -w`

if [ $B = 0 ]
then
echo NULL
else
count=`echo $A| nawk -F, {'print NF'}`
i=1
while [ $i -le $count ]
do
str[$i]=`echo $A| cut -d, -f${i}`
echo "${str[$i]}"
i=`expr $i + 1`
done
fi

any ideas?
