When you need to loop over a bunch of files and a pipe isn't feasible
then a for loop on the command line is useful.
<br>
<pre>
for VAR in LIST_OF_WORDS ;do   cmd1; cmd2; cmd3 etc ;done
</pre>
keywords: for in do done Semicolons needed unless newline:
<pre>
for VAR in LIST_OF_WORDS 
do   
cmd1
cmd2
cmd3
done
</pre>
for i in hello there world ;do echo $i ;done
<br>
for in in * ;do echo $i ;done
<br>
<pre>
for i in *
  do
    echo -e "$i : \c"
    head -1 $i
  done
</pre>
for i in /bin/* ;do file $i | grep -v ELF | grep -v symbolic ;done
