Hi all
Thanks in advance...........

Please help me for this issue............

I have a file it has 11 records . I used the command like ....

>$ wc -l file
11 file

I'm getting output like 11 file (no.of records along with filename)

here my requirement is, I want to display only no.of records without filename
like only 11.

can anyone please tell me which command I have to use?

because if I get this no.of records I have to comapre with some outfile
so shall I assign this no.of records to any variable ?

Thanks

try this

 
wc -l < file

otherwise, use awk, cut,...etc...

>$ wc -l < file
11

But I want to assgin this output to any variable?

I'm declaring like below.

j=wc -l < file
k=wc -l <outfile
 
if [ $j -eq $k ]
then 
  echo " both are same "
else
  echo " not same"
fi

my program is like this ... but it is giving error like

ex: line 13: -l: command not found
+ k=wc
+ -l
ex: line 14: -l: command not found

but giving the output properly...
can u please tell me y it is giving like this?

Thanks
Srivani

j=`wc -l < file`
k=`wc -l <outfile`

use back ticks

or use it like below

 
j=$(wc -l < file)
