In the basic regular expression specifying the search pattern in the sed substitute command:
are Pass=, Reject=, and All= matched by any of the expressions shown in red text between \( and \) pairs? No!
The BRE: abc\(123\)def will match any string that contains the characters abc123def contiguously and in that order. If that BRE is used to match a string in a sed substitute command, \1 in the replacement string will be replaced by the characters that matched the subexpression between the subexpression delimiters \( and \) (in this case the substring 123).
I have a log file with over 500000 lines and I want to use sed command to filter through the file and delete the first 5000 lines.
I have tried
sed -e '1,5000d' fileA.
where d is delete but this does not work. Any ideas ?

PAPS(1) General Commands Manual PAPS(1)NAME
paps - UTF-8 to PostScript converter using Pango
SYNOPSIS
paps [options] files...
DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
through the pango ft2 backend.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is
included below.
--landscape
Landscape output. Default is portrait.
--columns=cl
Number of columns output. Default is 1.
--font=desc
Set the font description. Default is Monospace 12.
--rtl Do rtl layout.
--paper ps
Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.
--bottom-margin=bm
Set bottom margin in postscript points (1/72 inch). Default is 36.
--top-margin=tm
Set top margin. Default is 36.
--left-margin=lm
Set left margin. Default is 36.
--right-margin=rm
Set right margin. Default is 36.
--help Show summary of options.
--header
Draw page header for each page.
--markup
Interpret the text as pango markup.
--encoding=ENCODING
Assume the documentation encoding is ENCODING.
--lpi Set the lines per inch. This determines the line spacing.
--cpi Set the characters per inch. This is an alternative method of specifying the font size.
--stretch-chars
Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
behaviour.
