What does the bash environment variable PATH control?
- AThe directories searched, in order, to find executable commands
- BThe directories the dynamic linker searches for shared libraries
- CThe current working directory used by relative file paths
- DThe list of directories backed up by the system's cron jobs
Why this is the answer
PATH is a colon-separated list of directories the shell searches to locate a command typed without a full path. Library lookup uses LD_LIBRARY_PATH, and the working directory is tracked separately as PWD.
