Question

Write a script to check if the current user has any processes that have been running for more than one hour. If the process has ran for more than one hour, the script should kill the process. However, the script should not kill the bash shell (that the script is run from (or any others). Commands that you may need to use might include ps, tr, tail, cat, cut, paste, echo, expr, date and kill.

Note: Your script must avoid killing all bash shells. Bash is most frequently listed in the results of ps as just bash, but can be listed as /bin/bash, or as part of a running script as /bin/bash script1.sh. It’s also possible that it is being run out of some nonstandard directory (like ~/bin/bash for a custom version).

Note: This program will kill your graphical environment if you are using one. If you really want to see if it works, run it from console mode.
