Can I write a string into file from shell?
Hi ,
If I used this
wc -l *.dat ,it will count number of line in these files like this
1234 test1.dat
2345 test2.dat
3456 test3.dat
7035 total

can I add '|'(pipe) in the middle of those number and string like this
1234|test1.dat
2345|test2.dat
3456|test3.dat

Thanks in advance.

Or:

Code:
awk 'NR>1&&FNR==1{print n,f}{
	f=FILENAME;n=FNR
}END{
	print n,f;print NR,"Total"
}' OFS="|" *.dat
