Top Forums UNIX for Dummies Questions & Answers how to tail last 500 lines and vi them? Post 302262480 by Lakris on Thursday 27th of November 2008 02:28:25 PM

Hi, do You need to edit the output? Redirect it to some tempfile and edit it,

Code:
tail -500 bigfile > /tmp/tempfile; vi /tmp/tempfile

Otherwise view it with less, like in

Code:
tail -500 bigfile | less

or view it continuously with less,

Code:
less +F bigfile

And there are more ways... Your example doesn't work because You pipe the output of tail to small_file and Your shell believes that to be a command, but I guess it isn't. I think a redirection is what You want.

TAIL(1) 						      General Commands Manual							   TAIL(1)

NAME
tail - deliver the last part of a file SYNOPSIS
tail [ +-number[lbc][rf] ] [ file ] tail [ -fr ] [ -n nlines ] [ -c ncharacters ] [ file ] DESCRIPTION
Tail copies the named file to the standard output beginning at a designated place. If no file is named, the standard input is copied. Copying begins at position +number measured from the beginning, or -number from the end of the input. Number is counted in lines, 1K blocks or characters, according to the appended flag or Default is -10l (ten ell). The further flag causes tail to print lines from the end of the file in reverse order; (follow) causes tail, after printing to the end, to keep watch and print further data as it appears. The second syntax is that promulgated by POSIX, where the numbers rather than the options are signed. EXAMPLES
tail file Print the last 10 lines of a file. tail +0f file Print a file, and continue to watch data accumulate as it grows. sed 10q file Print the first 10 lines of a file. SOURCE
/sys/src/cmd/tail.c BUGS
Tails relative to the end of the file are treasured up in a buffer, and thus are limited in length. According to custom, option +number counts lines from 1, and counts blocks and characters from 0. TAIL(1)
