A Storage Administrator ran a PSTCLI command on a Linux host. The error " -bash: pstcli: command not found" appears. How is the problem resolved?

The error message -bash: pstcli: command not found is a standard Linux shell error indicating that the pstcli executable cannot be found in any of the directories specified in the PATH environment variable. The correct and standard procedure to resolve this is to modify the PATH variable to include the directory where the pstcli binary is located. This is typically done by adding an export PATH command to a shell initialization file (e.g., ~/.bashrc or ~/.bashprofile), ensuring the command is available in future shell sessions.

A. PSTCLI.sh is not a standard shell initialization file for environment configuration; modifying it is improper and may not be persistent.

B. The error does not imply a corrupted or failed installation, but rather a shell configuration issue. Reinstalling the software is unnecessary.

C. This describes a choice made during the installation process, not a method to resolve a pathing issue for an existing installation.

Step 5.

The document explicitly states: "To run the pstcli commands from any directory

add the installation path to the PATH environment variable. For example: export PATH=$PATH:/opt/dellemc/pstcli/bin". This directly supports the correct answer (D) as the official procedure.

"The Shell".

This academic-level text explains that a "command not found" error occurs when the shell searches the directories in the PATH variable and fails to find a matching executable. It confirms that the solution is to add the command's directory to the PATH.
