Hi, I have observed the following behaviour when a while-read loop is called in a shell script in sbox2 prompt.
================================================================== #! /bin/sh # Sample program # Requisites # Compile a sample hello.c in the CWD logfile=RESULTLOG rm -rf $logfile while read one two three; do echo "-------------------------------------" >> $logfile if [ $? -eq 0 ]; then echo "while read succeded" >> $logfile echo "one = $one" >> $logfile echo "two = $two" >> $logfile echo "three = $three" >> $logfile fi for i in $one; do echo "DEBUG MESSAGE" >> $logfile ./hello >> $logfile done done <<EOF a for an apple b for a ball c for a cat d for a dog e for an elephant f for a fox g for a goat h for a horse i for an ice-cream EOF echo "one outside the loop = $one" >> $logfile ================================================================== Expected behaviour: Enter the while loop 9 times and read the 9 lines Problem: The while loop is executed only once - If a new executable like 'hello' is called inside the while loop, the loop is executed only once. - Otherwise, the test runs as expected. This happens only in the sb2 shell. If the same is run on a Linux bash shell/Target(ARM) shell the script runs fine. Please let me know if such a behaviour is already seen in scratchbox and provide your inputs Thanks & Regards, Chandana.
