First off, Thank you all for the knowledge I have gleaned from this site!
Deleting Records from a text file... sed paragraphs
The following code works nearly perfect, however each time it is run on the log file it adds a newline at the head of the file, run it 5 times, it'll have 5 blank lines at the head of the file.
I have been unable to figure out why or how to prevent it.
Newlines should be after the record, not before.
Also, How big of file can sed handle like this??
The code: (I have made it into a here doc for example)
Code:
#!/bin/sh
matchitem=' Using archive: /mnt/Raid/test/Backup_20090824@051500.tbz'
item2del=$(echo "${matchitem}" | sed 's:[]\[\^\$\.\*\/]:\\&:g')
sed -n '
/Backup started:/ b paragraph
H
$ b paragraph
b
:paragraph
x
/'"${item2del}"'/!p' <<EOF

So I added $, which I thought matches the ends on lines, but its not working, like for example I have have... (5 Replies)

LEARN ABOUT DEBIAN
fixnt
fixnt(1) Debian fixnt(1)NAME
fixnt - Filter for the Windows NT postscript printer driver.
SYNOPSIS
fixnt < BADFILE.ps > GOODFILE.ps
DESCRIPTION
The Windows NT postscript driver has a tendency to make broken postscript files, that are incompatible with psutils. fixnt is a filter
that fixes these problems, allowing the use of psnup(1).
The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout. It has no other form for invocation
and takes no options on the command-line.
OPTIONS
fixnt takes no options.
BUGS
fixnt does not check for NTPSOct94. For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
sed 's/NTPSOct94/NTPSOct95/g'
This is particularly important for Windows NT 3.5 users.

REPORTING BUGS
Report bugs to the Authors, but avoid sending large postscript files.
Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
