SSC IMD SA Mock 03 – Question 121

Which of the following commands is/are used to create files in Linux?
Commands:
i) touch
ii) cat
iii) head
iv) finger

• i, ii and iii only
• ii, iii and iv only
• i and ii only
• i only

In Linux/Unix systems:
– touch (i): Used to create a new, empty file if it does not already exist (e.g., touch myfile.txt), or update timestamps if it does.
– cat (ii): Used with the output redirection operator (cat > myfile.txt) to create a new file and write text into it from the terminal.
– head (iii): Used to output the beginning lines (default first 10 lines) of existing files; it cannot create files.
– finger (iv): A user information lookup program that displays login details of system users; it does not create files.

Therefore, only touch and cat (i and ii) can be used to create files. The correct option is c).
