I have a source code to find a number of words and characters in a file:
#!/bin/bash w=0 cc=0 for i in `cat $1` do j=$i echo $j w=$(($w+1)) c=`expr $j:'.*'` cc=$(($cc+$c)) done echo "no of characters" $cc echo "no of words" $w
But when I run it in the terminal the following error message is displayed^
./countWordChar: line 10:
0+hello:.*: syntax error in expression (error token is
no of characters 0
no of words 1
The 10th line in the code is
cc=$(($cc+$c)). Apparently the c variable's value is not a number of characters of a word but the word itself.
And my 1.c file content is like that:
hello world hello
What's wrong in the code?
PS. I know that there are builtin commands to count characters in a file but I must use the previous code according to my task.
