Modify text file using shell script
Hi,

I have a text file which is following format -

COL VAL
ABC 1
ABC 2
ABC 3
ABC 4
ABC 5

My requirement is to search for a particular value (provided by user) in the file and comment the previous entries including that as well.

E.g. If I search for number 3, then the output file should be similar to -

COL VAL
#ABC 1
#ABC 2
#ABC 3
ABC 4
ABC 5

Kindly suggest with some options. Thanks for your time.

NAME

       mmseg - maximum matching segment Chinese text.

SYNOPSIS

       mmseg -d dict_file [option]... [corpus_file]...

DESCRIPTION

       mmseg is a tool for segmenting Chinese text into words using maximum matching algorithm. mmseg segments corpus_file, or standard input if
       no filename is specified, and write the segmented result to standard output.

OPTIONS

       -d dict_file
	   Use dict_file as lexicon. A default lexicon can be found at /usr/share/sunpinyin-slm/dict.utf8.

       -f,--format (text|bin)
	   Output Format, can be 'text' or 'bin'. default 'bin'.  Normally, in text mode, word text are output, while in binary mode, binary short
	   integer of the word-ids are written to stdout.

       -s, --stok STOK_ID
	   Sentence token id. Default 10.  It will be written to output in binary mode after every sentence.

       -i, --show-id
	   Show Id info. Under text output format mode, attach id after known words.  If under binary mode, print id(s) in text.

       -a, --ambiguious-id AMBI-ID
	   Ambiguious means ABC => A BC or AB C. If specified (AMBI-ID != 0), The sequence ABC will not be segmented, in binary mode, the AMBI-ID
	   is written out; in text mode, "<ambi>ABC</ambi>" will be output. Default is 0.

NOTES

       Under binary mode, consecutive id of 0 are merged into one 0.  Under text mode, no space are inserted between unknown-words.
