I would like to redirect the command executed along with the output to a file.

for example: #ls >ls_out.txt

ls_out.txt should be something like :

ls

file1 fil2

Thanks!

  1. I use a function for this kind of thing:

    echocmd() {
    echo "$@"
    "$@"
}

    Then

    $ echocmd ls -ltr > ls_out.txt

    You could use "script" command: Something like this:

    localhost:test_sf user1$ ls
file1   file2   file3
localhost:test_sf user1$ script ls_out.txt  #starting script command ls_out.txt will contain output
Script started, output file is ls_out.txt
bash-3.2$ ls 
file1       file2       file3       ls_out.txt
bash-3.2$ exit
exit

Script done, output file is ls_out.txt
===================================================================================
localhost:test_sf user1$ cat ls_out.txt  #verify the contents now.
Script started on Wed Dec 18 12:05:23 2013
bash-3.2$ ls 
file1       file2       file3       ls_out.txt
bash-3.2$ exit
exit

    You will just have to get rid off "bash-3.2$ exit exit" piece.
