Tail Command (Linux)

Options:

• -f :
• -n, –lines=Koutput the last K lines, instead of the last 10; or use -n +K to output lines starting with the Kth
  • Note: the ‘+’ has a significance.
    • If there is no ‘+’,  then tail counts K lines from the bottom of the file
    • If there is a ‘+’,  then tail counts K lines from the top of the file
• -q, –quiet, –silentnever output headers giving file names

Tips:

• With -n and -q, tail can be pretty useful in concatenating files without the header.

  • Unfortunately this deletes the header from all files.
