thank you

sorry for later

Code:

if ($# < 1) then ----> we control parameters count
   echo paramter broken ---> if parameters less than 1 echo message and quit
   exit
endif
set b = ($*) ---> all parametres ($*) to send an array for process easier all 
( so if write --> # ./myscript host1 host2 ...-->  (" $* = host1 host2 ..." ) )
 
foreach i ( $b ) ----> and for loop \for each parameter process
  echo $i host informations  ---> writing messages related our hosts name
  echo "*******************"
   if ( " `/usr/sbin/ping $i 5 | grep alive`" == "" ) then ---> if ping is `not` successfull in 5 seconds
      echo ping broken ---> writing messages related our hosts
      echo ""
   endif
   if ( "`nslookup $i | grep find`" == "" ) then  ---> if nslookup is successfull
      echo $i host records  ---> writing messages related our hosts
      echo "*************"
      nslookup $i  ---> and nslookup result for (each) host because we are still for - loop
   else ---> if nslookup is `not` successfull
      echo $i host does not match any records ---> writing messages related nslookup failure message
      echo "********************************"
      echo ""
      shift ---> and parameter shift (actually `not neccassary` because we use just b parameter for this to below define `set b = ($*)`
however this means $*="host1 host2" just then $*="host2"
   endif
end

set_color

set_color(1)                                                           fish                                                           set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
