Shell Programming and Scripting

Im trying to make a bash file that will take another file and count how many lines there are and then count how many words are in each line.

Any help would be great.

To calculate how many lines you can use,

Code:

wc -l filename.txt

To calulcate how many words /line,

Code:

awk '{print NR NF}' filename

Code:

sed -n '$=' filename

Thanks

Thanks, but I'm unsure as to how to go about putting this in a script.

Thanks.

seems like a home work

read about the variable assignment in shell script

Variable Assignment

Ok i have researched this a little and coming across a few problems.

1. When this code is used.

Code:

#!/bin/bash

lc=0;
el=0;

while read 
do
el= wc -w; 
lc=$(($lc+1));
echo "$el";
echo "$lc";
done < "text.txt"

Its doing a total word count and not a line by line echo with the line number then the amount of words.

2. so i tried this.

Code:

#!/bin/bash

lc=0;
el=0;

while read
do el= wc -w;
echo "$el"
done < "text.txt"

while read
do lc=$(($lc+1));
echo "$lc";
done < "text.txt"

and still the wc is not going line by line im thinking it because wc is a built in function is this correct? if so what is an alternative i can use. Also with both word counts wc -w it is skipping the first line regardless of what is in it.

Thanks

Code:

el= wc -w;

the above will not work.

because for the wc command, you need the file name or any input

Code:

wc <options> filename

or

Code:

echo "This is test" | wc -l

and also, you need to use the backtick when you are trying to execute the command and strore the value.

eg:

Code:

count=`echo "This is the test" | wc -w`
echo $count
