I am running scriptA.sh as root. Inside the script I need to echo data into FileA. FileA is owned by user1. FileA is located under /usr/local and has the following permissions:
-rw-r----- 1 user1 group
FileA permissions cannot be modified. Right now, when I run scriptA I get permission denied on FileA. Is there anyway to get around this inside the script?
Psuedo code from scriptA that writes to FileA:
function update_FileA()
if [ condition ] then
echo "XYZ data" >> FileA
else
echo "ABC data" >> FileA
fi
Update: Tried a few things. I tried to vi FileA as user1 and as root and I was able to successfully edit. Its only when trying to edit the file through the script write access is denied.

echo foo | sudo -u user1 tee FileA, perhaps. How exactly are you executing the script and how exactly are you echoing data to the file?

Root has permission to read all files, can you show the contents of scriptA.sh

Or perhaps the file has the "immutable" attribute set? (check with the lsattr command) Or maybe the system has detected some filesystem corruption and switched to read-only mode?
