Display a block of text with vim with offset, like with AWK

vim -e -s -c 'g/start_pattern/+1,/stop_pattern/-1 p' -cq file.txt
By using vim, you can also filter content on stdout, using vim's extra power, like search pattern offset! No more awk of course, sorry. details : -e ex mode -s silent -c 'ex command' : global + start and end pattern + offset print (p) -cq : quit
Sample Output
$cat file.txt

here too

pipo
et
molo

ski

  • I find this terribly useful for grepping through a file, looking for just a block of text. There's "grep -A # pattern file.txt" to see a specific number of lines following your pattern, but what if you want to see the whole block? Say, the output of "dmidecode" (as root): dmidecode | awk '/Battery/,/^$/' Will show me everything following the battery block up to the next block of text. Again, I find this extremely useful when I want to see whole blocks of text based on a pattern, and I don't care to see the rest of the data in output. This could be used against the '/etc/securetty/user' file on Unix to find the block of a specific user. It could be used against VirtualHosts or Directories on Apache to find specific definitions. The scenarios go on for any text formatted in a block fashion. Very handy.

  • -n reads input, line by line, in a loop sending to $_ Equivalent to while () { mycode } -e execute the following quoted string (i.e. do the following on the same line as the perl command) the elipses .. operator behaves like a range, remembering the state from line to line.
