bash - Redirect output of a file to the write command -


i trying redirect standard outupt of file write command , display contents of file (with color changes) in terminal of other user.

the contents of file output displayed (filename menu_sys.sh)

echo -e "\t\t\033[4;41m welcome internal messaging system \033[0;0m"

when use code $ sh menu_sys.sh | write 680613 output ^[[4;41m welcome internal messaging system^[[0;0m

tried using standard output redirection using &1> did not work

but need output in formatted condition.

if write command allowed arbitrary control characters sent terminal of user, flagrant security problem. in fact, sanitizes contents of message sent render control characters harmless. that's why see esc control character 2 ascii characters '^' , '[' on other user's terminal.

as aside: jonathan leffler mentioned, "standard output of file" doesn't make sense. appear doing sending standard output of command (echo) write command, not "standard output of file". or if meant send contents of file other user (using command write 680613 < somefile) ok too.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
