bash Linux how to get first or last letters of a word

To get the first X letters of a word:

It's very simple you can just pipe it to head with

  • -c 1 (gives the first letter and so on)
  • -c2 (2 gives the first 2 letters). 

 echo "dsjfsdlksjdklf;jlsd;kflasdj;kl"|head -c 2

Returns ds
 

To get the last X letters of a word:

Now we use tail with -c but it works differently.  You will want to start with 2 otherwise you will get the end of the string which is nothing.

 echo "dsjfsdlksjdklf;jlsd;kflasdj;kl"|tail -c 2

Returns "l"

 echo "dsjfsdlksjdklf;jlsd;kflasdj;kl"|tail -c 3

Returns "kl"
