To locate a missing file with only a partial name known, the best tools to use in a Linux environment would be grep and find.

grep: This command is used to search the contents of files for a specific pattern. While grep itself might not be the first choice for finding file names, it can be combined with other commands (like ls or find) to search within file lists or contents.

find: This command is used to search for files in a directory hierarchy based on various criteria like name, size, modification date, etc. find can be used to search for files by partial name by using wildcards in the search pattern.

cat (A) is used to concatenate and display the content of files. df (B) displays the amount of disk space used and available on filesystems. ps (D) shows information about active processes. dig (E) is used for querying DNS name servers. top (G) displays Linux tasks and system performance information. None of these tools are directly suited for finding files by partial names.

When an Android device starts exhibiting issues like frequent crashes and rapid battery drain after downloading an application, the first step should be to address the immediate cause:

Uninstall the game application: Since the issues started after the game application was installed, removing it is a logical first step. Unwanted or malicious applications can cause such symptoms by running harmful processes in the background or exploiting system resources.

Install the latest security patches: Keeping the device updated with the latest security patches is crucial for protecting against vulnerabilities that could be exploited by malicious software. Updating can resolve existing security flaws and improve device stability.

When troubleshooting a Windows system that is experiencing issues during the OS loading phase at startup, enabling boot logging is a practical step. Boot logging creates a record of all drivers and services that are loaded (or attempted to be loaded) during the startup process. This record, typically named ntbtlog.txt, can be reviewed to identify any drivers or services that failed to load, which could be contributing to the startup issues. This diagnostic step helps pinpoint the problematic component(s) and facilitates targeted troubleshooting to resolve the OS loading issues.

For a company looking to transition away from face-to-face meetings, videoconferencing and screen-sharing software would be most beneficial.

Videoconferencing software allows participants to conduct virtual meetings with audio and video capabilities, effectively simulating a face-to-face interaction without the need for physical presence. This can greatly reduce travel costs and time while maintaining the personal touch of meetings.

Screen-sharing enables participants in a virtual meeting to view one another's computer screens in real time. This is particularly useful for presentations, collaborative work, and troubleshooting, as it allows for a more interactive and engaging meeting experience.

Both technologies support the company's goal of leveraging modern technology to enhance communication and collaboration while reducing reliance on physical meetings.
