Help me please to fix my error
Can you help me to fix my error please?! I checked the code and I think there is no mistake, but when I run it gives me error such
line 1: /Users/Manu/trials/hosts: is a directory
sort: open failed: /Users/Manu/trials/hosts/*: No such file or directory
Help me please...

mycode NAME value.
It creates file with NAME and value inside the file (first line).
Second line iin file is number generated by my code.
ex:
my_code Manu rtry466ry
-> cat Manu
rtry466ry
192.168.1.1.

mycode:

Code:
DIR=` /Users/Manu/trials/hosts `
 for i in $1 $2
        do
        if [ "$(ls -A $DIR)" ]
              then
              sort /Users/Manu/trials/hosts/* | head -2 |  tail -1 |
                    while IFS="." read A B C D
                    do
                    if [ $((++D)) -eq 255 ]
                        then
                        ((C++));
                         D=0;
                    fi
    
              echo $2 "\n" $A.$B.$C.$D. >/Users/Manu/trials/hosts/$1
              done
          else 
            echo $2 "\n" "192.168.1.1." >/Users/Manu/trials/hosts/$1
              fi
              done

Use double quote instead of backquote :
Code:
DIR="/Users/Manu/trials/hosts"

I think those err msgs are self explanatory and correct. Try to check your files/directories.

As I can't relate your spec text to your script, I'm afraid I can't help further. Just an aside: Be aware that IP host numbers 0 and 255 are special addresses not to be used generally.

I cant fix it people. Help me please. Really confused....
It gives me nothing but ideally:

sh mycode Manu tt-44-44
It creates file Manu
cat Manu
tt.44.44
192.168.1.1.

sh mycode Chris gg-22-22
It creates file Chris
cat Chris
gg-22-22
192.168.1.2.
But my code even does not increment last digit even its clear in code that i increment it..... Help please ;(

Code:
DIR="/h/Manu/HOME/hosts"
 for i in $1 $2
        do

        if [ -d "$DIR" ]
              then
              sort /h/Manu/HOME/hosts/* |  tail -2 | head -1
                    while IFS="." read A B C D
                    do

   if [ $((++D)) -eq 255 ]
   then
   ((C++));
   D=0
 #     if [ "$D" != 255 ]
  #   then
   #  D=` expr $D + 1 `
    #   else
     #C=` expr $C + 1 `
    # D=0


fi




              echo $2 "\n" $A.$B.$C.$D >/h/Manu/HOME/hosts/$1

 done
          else
            echo $2 "\n" "192.168.1.1" >/h/Manu/HOME/hosts/$1
              fi
              done

That code is an absolute mess. It's almost as if you're trying to make it difficult for us to help. The very, very least you can do is use sane indentation.

I didn't scrutinize it, but two things stand out in your most recent post. (1) You are not piping sort|tail|head into the while-loop. (2) You don't use $i anywhere (perhaps that's intentional).

On a general note, you have not made any effort to provide useful feedback for the suggestions given. Have you confirmed that the directory exists and that there are files in it, per post #5? If you can't be bothered to help us account for the error messages that you report (when you report them), how do you expect us to help you fix the problems?

I suggest you be specific instead of vague.
