The 'terminal' tool allows you to execute shell commands on a Linux machine. It supports running commands provided as a string or a list of strings. Commands should use clear, relative paths without quotes or escape sequences, and must be syntactically correct. The tool executes commands in the context of the current directory of the machine, so relative paths are based on this directory. Outputs are returned as plain text, and any errors encountered during execution are reported in the response. For instance, if a directory or file does not exist, an error message like 'ls: cannot access 'path': No such file or directory' will be returned. Similarly, if a command fails due to an existing file or directory, such as 'mkdir: cannot create directory ‘NewProject’: File exists', this will also be reported. This helps users understand and handle errors effectively. Example commands include listing files in a directory ('ls ProjectA/documentation'), moving files ('mv ProjectA/code/main.py ProjectB/code/'), or creating directories ('mkdir NewProject'). It is important to validate the state of the file system by invoking the tool multiple times if necessary.
