Final answer:
To find a file containing a specific string in Linux, use the 'grep' command.
To navigate to another directory, use the 'cd' command. These commands help users manage and locate files within the Linux filesystem.
Therefore, the correct options are: A). grep and F). cd
Step-by-step explanation:
The Linux command line offers various tools to search for files and navigate directories. To find a file that contains a specific string, the grep command is used. This command can search through one or more files to find lines that match a specified pattern.
After locating the file, the cd (change directory) command is used to navigate to different directories within the file system.
To use grep, you might enter a command like: grep 'specific string' filename.txt, which would search for 'specific string' in 'filename.txt'. To change to another directory, you would use: cd /path/to/directory. This would change your current directory to '/path/to/directory'.
String command in Linux will return each string type of characters that are printable in the file. It is mainly used in determining the file's contents and extracting the text from binary-type files. A string contains a sequence of finite characters and can also be considered one character.
