i always used:
	grep -n '^' file1 > file2

but that's just me, i guess.

Does
	awk '{print NR "\t" $0}' file1 >file2
not work?

Another of my methods was
	grep -n '^' file1 | sed 's/:/	/' > file2

Re: [9fans] sed

I had a list of several ways to do it, of which the second was
	awk '{print NR "\t" $0}' file1 >file2
but decided the shortest was also the most straightforward.
	pr -t -n file1 > file2

Is there a different way to do the following under Plan9?

	sed = file1|sed 'N;s/\n/\	/' >file2

		or

	cat -n file1 >file2

Both would insert line numbers in file2 from file1.
Sorry if this is a basic question.

"rob pike" <rob@plan9.bell-labs.com>:

	pr -t -n file1 > file2

make sure you use
	pr -t -n file1 > file2
	pr -n -t file1 > file2
	pr -tn file1 > file2
but not
	pr -nt file1 > file2

Re: [9fans] sed

[rob pike]

	pr -t -n file1 > file2
