Java String with different length
let image that we have string:
QQQQQQQ:ABCDE:FFFFFF:GGGGG

in second field can be 0 or 5 characters

if A exist i need set variable ex: VAR=yes
if B exist i need set variable ex: VAR1=yes
if C exist i need set variable ex: VAR2=yes
etc ...
if second field is empty no variable to set
if in second field exist A and C only i need set VAR & VAR2 no others

can anybody help with that?

Something like this?
Code:
#!/bin/ksh

str="QQQQQQQ:ABDE:FFFFFF:GGGGG"

set $(echo $str | tr ':' ' ')

if [[ $2 =~ "A" ]]
then
  VAR=yes
fi

if [[ $2 =~ "B" ]]
then 
  VAR1=yes
fi

if [[ $2 =~ "C" ]]
then 
  VAR2=yes
fi

Why did you use [[...]] instead of [...]
Code:
if [[ $2 =~ "C" ]]

Code:
if [ $2 =~ "C" ]

Quote:
str="QQQQQQQ:ABC:FFFFFF:GGGGG"

parms=$(echo $str | awk -F: '{print $2}')

[[ ! -z $parms ]] && {

echo $parms | grep -i "A" >/dev/null 2>&1
[[ $? -eq 0 ]] && VAR=yes

echo $parms | grep -i "B" >/dev/null 2>&1
[[ $? -eq 0 ]] && VAR1=yes

With the test command [[...]] you can use extended regular expressions like [[ $2 =~ "A" ]].

The test command [[..]] with an ERE works with ksh93 not with ksh88.
