Inserting ouput into a file using redirection
Hallo Team,

I would like to redirect an output from a file into another file. Here are the two commands/files.

Code:
-bash-3.2$ cat lack.csv
lemontwistpax
-bash-3.2$ ll -ltr BW*|tail -1

-bash-3.2$ ll -ltr BW*|tail -1 << cat lack.csv
>
>

i would like to append the output from lack.csv into whatever
file would appear when i run
Code:
ll -ltr BW*|tail -1
