I have a file like

foo.txt

xxx B=C D: A
yyy F=H D:A
zzz K=L D: A
fff M=H D:/llll
kkk S=D D: /kkkkk

this is what I try to get;

xxx B=C; D: A ;pass
yyy F=H; D:A ;pass
zzz K=L; D: A ;pass
fff M=H; D:/llll ;try
kkk S=D; D: /kkkkk/bb ;try

The second part of line which starts with "D:",if starts with "/", it should be write "try" else it has to write "pass" end of the line for every line in it.

I can read file like this but there is spaces which is another problem

In addition after "D:" always starts with "A" or "/".

I tried while loop but I have not succeeded.

cat /tmp/foo.txt | cut -d ":" -f,2

Output

 A (one empty space)
A (none)
 A (three empty space)
/llll (none)
 /kkkkk/bb (two empty space)

This is a example what I have tried

while read -r line;
do 
if [[ $line ]]; then
 echo $line "try"
else
 echo $line "pass" 
fi
done < foo.txt

You can't write in the same file, I would recommend to create a new file and then rename it.

tmpFile="/tmp/foo2.txt.tmp"

cat /tmp/foo.txt | while read line; do
 isSlash=$(echo $line | cut -d ":" -f2 | awk 'print $1' | grep -c ^"/")
 if (( $isSlash )); then
 echo "$line ;try" >> $tmpFile
 else 
 echo "$line ;pass" >> $tmpFile
 fi
done

mv $tmpFile /tmp/foo.txt

You can use awk, which makes it very easy to accomplish what you want:

awk '!/D: *//print $0 " ;pass"; next print $0 " ;try"' foo.txt

Output:

xxx B=C D: A ;pass
yyy F=H D:A ;pass
zzz K=L D: A ;pass
fff M=H D:/llll ;try
kkk S=D D: /kkkkk ;try

This basically matches every line not containing D: and / and appends ;pass to it, then skips to the next line. Otherwise it appends ;try to it.

sed OK?

$ sed '/D: *A/ s/$/t;pass/; /D: *// s/$/t;try/' file
 xxx B=C D: A ;pass
 yyy F=H D:A ;pass
 zzz K=L D: A ;pass
 fff M=H D:/llll ;try
 kkk S=D D: /kkkkk ;try
