with this code the problem is that in
1st loop guessed was e
display that -e----
2nd loop when guessed was d
display that --d---
and the desire sesult was -ed----
any idea???
This is nog my experience:
This is what happens when I run the code:
Code:
e
-e-----
d
-ed----
o
-ed-oo-
a
-ed-oo-
b
bed-oo-
r
bedroo-
m
bedroom

can you explain me this 2 lines what are you doing?
using this code if [ -n "$char" ] any char press the lifes decrease we want to decrease when the guessed is wrong any idea
and why use this guessed="$guessed$char"
can i ignore this line guessed="$guessed$char"
and last line wrote this echo $word|sed "s/[^$char]/-/g"
Sure it is. I did not want to spoil your fun by writing all the code for you. I just tried to show a basic mechanism. The
Code:
if [ -n "$char" ]
means the if it is non-zero then decrease lives this is so that if a user enters enter by accident without a character lives does not decrease. You could replace that statement with a test to see if the character is part of $word and bob is your uncle.
Quote:
why use 2 (( here $((lives -1)) and why $ is out;
The $(( ... )) construct is used for calculations. Inside the double parentheses you can use variables without the $-sign (you can still use it if you wish. The $(( ... )) is a more modern construct. I hardly use the oldfashioned expr statement anymore.

sorry for my question but i want to learn i think stupid to write somenthing don't understanding maybe i need to use many of commands in the future
Don't be sorry that is what this forum is for . It is excellent that you really want to understand the code..

In Addition the decrease must doing when i press wrong guess
---------- Post updated at 10:31 PM ---------- Previous update was at 08:28 PM ----------
one though is to split the word to a table an with for i check if char is not included to table decrease the lifes
for example in c language i can write this
for (i=1;i<=sizeof(tablep);i++)
{
if (char != tablep[i])
lives--;
}
does anyone how to make it with bash
You can use a case ... esac statement to do that or use [[ ... ]] and pattern matching with asterisks or use the pattern matching operator ~= There are many ways... Good luck.

word=bedroom
len=$[#word]
lifes=7
while [ lifes -gt "0" ];do
read a
for i in $( seq 1 $(( $len )) )
if [ a != ${word[i]}
then lives=$(( lives -1))
fi
echo $i
done
in this code it is necessary to create table for example
Code:
word=bedroom
len=$[#word]
lifes=7
for i in $( seq 1 $(( $len )) )
do
t[$i]=$echo "${word}" | cut -c$(($i+1)) )
done
while [ lifes -gt "0" ];do
read a
for i in $( seq 1 $(( $len )) )
if [ a != ${t[i]}
then lives=$(( lives -1))
fi
done

just found the solution i use one var as boolean false or true
if i found in table the character i make the var true and after finidh the loop decrease lifes
I'd do something like this. You can take it from there:
Code:
guessed=""
lives=7
wordlist=./hangmanword
# See if wordfile exists - Elegxos gia to an to wordfile yparxei kai mporei na diavastei
if [ ! -r $wordlist ]; then
echo "$wordlist den yparxei h den vrethike"
exit 1
fi
# pick a (kind of) random word - dimiourgia tou generator
nrofwords=$(wc -l<$wordlist)
word=$(sed $((RANDOM%nrofwords+1))!d $wordlist)
# Here we go
while [ $lives -gt 0 ]; do
echo "you have $lives lives left"
read char
case $word in
*$char*) guessed="$guessed$char";;
*) lives=$((lives - 1)) ;;
esac
solution=$(echo $word|sed "s/[^$guessed ]/-/g")
echo $solution
if [ "$solution" = "$word" ]; then
echo "You Win"
exit
fi
done
echo "You Loose"
echo "The word was $word"
