Don,
Thanks,
The desired script should find lan5:5 , and then to decide the [8] string, then remove all the lines having [8] entires. Can we put the condition for finding lan5:5 and then do the editing on the file to remove the lines.
- As without seeing the file I do not know if the lines I am going to remove has the pattern of [8] , but what I know is lan5:5 . Hope you got it.
I'm sorry, but I don't understand your requirements. It is obvious that we have a language barrier. Are you saying that you:
want to find a line that contains lan5:5,
find a digit string between [ and ] on that line, and then
remove every line in the file that contains that digit string between [ and ]?

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
