Hi,
add_num=`expr $int_num + 1 1>/dev/null 2>&1`
if [ "$?" -ne "0" ]
some case exit status is 1552 for expr even though the argument is integer
.Initialy i checked
if [ $?-ne 0 ],but this shows the above error so, i am planning to use
kms=$?
if [ $kms -eq 1 -o $kms -eq 2 -o $kms -eq 3 ]
instaed of
if [ "$kms" -ne "0" ] *is it fine or will it make issues.
* The mannual says
info expr|more
Exit status:
0 if the expression is neither null nor 0,
1 if the expression is null or 0,
2 if the expression is syntactically invalid,
3 if an error occurred.
Regards,
Salih
