I have updated the PATH environmental variable on a Redhat distribution but after reboot, the path is gone.
To add the path:
PATH=/opt/rh/mysql55/root/usr/bin export PATH echo $PATH /usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/opt/rh/mysql55/root/usr/bin reboot removes the path
echoing after
/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
