Increase of memory usage by running bash script.
1. Use a WRL 5 plaform project and boot up a target
2. Use the following script on the target to reproduce the issue:
#!/bin/bash
while [ 1 ];
do
prompt="hello:";
read -e -n 500 -p "$prompt " command;
echo $command;
done
3. Use the attached InputData.txt file. Copy paste the content of InputData.txt file while script from step 2 is running. Please see below example:
root@localhost:~# ./script.sh
hello: {}]Wo{]Wuk[u}}o_]{Core,bin,dev,e{w{_om}{Core,bin,dev,e{tc,xport},gep3_firmware,home,l{ib{,64},ogs},m{edia,nt},opt,proc,root{,_fs_from},s{bin,ys},tmp,usr,}k{Core,bin,dev,e{tc,xport
... trimmed output ...
4. In a different console( e.g.: ssh console) run the following command in order to observe memory:
top -b | grep script.sh
5. In order to see the memory value increasing repeat the copy paste several times while the script from step 2 is running (please find attached my top.log file)
