Displaying number of lines from file

shivanete · #1 (**permalink**) 12-09-2008

Hi,

I am using below command to display the number of line, but its returning no of lines along with file name.

But i want only no of line in the variable p.

Please help me on this?

p=`wc -l "text file"`
echo "$p"

zaxxon · #2 (**permalink**) 12-09-2008

Code:

p=`wc -l < text file`
echo "$p"

shivanete · #3 (**permalink**) 12-09-2008

but p returning values with leading space. how could i avoid those leading space?

It does show no leading blank in my case after adding the redirection. You can always just pipe it into for example:

Code:

..| awk '{print $1}'

or something.

you may want to consider using this command instead:

Code:

 sed -n '$=' filename
