Which command would you use to search for a file by name starting from a specified path?

• A. grep -R "filename" /path
• B. locate "filename"
• C. find /path -name "filename"
• D. ls -R /path | grep "filename"

Answer: (C)

To search for a file by name starting from a specific directory, you’d use the find command because it traverses the directory tree from the given starting point and checks each entry against a name pattern. Specifically, find /path -name "filename" tells it to descend into /path and all its subdirectories and return any items whose name matches the pattern exactly. The -name option uses shell-style wildcards, and it’s case-sensitive by default (use -iname for case-insensitive searches). This makes find the precise tool for locating a file by name within a chosen path. Other options aren’t as suitable: grep -R would search inside file contents, not by the file’s name. locate relies on a prebuilt database and isn’t restricted to a starting path or guaranteed to reflect recent filesystem changes. ls -R combined with grep depends on listing all results and parsing output, which is slower and less reliable.
