With GNU grep
If the matching lines are exactly the same, you can require a precise match with a further -x option.
A further -n option will indicate the line numbers and if it's a matched line or a neighbor line.

tabs
TABS(1) BSD General Commands Manual TABS(1)NAME
tabs -- set terminal tabs
SYNOPSIS
tabs [-n | -a | -a2 | -c | -c2 | -c3 | -f | -p | -s | -u] [+m[n]] [-T type]
tabs [-T type] [+[n]] n1[,n2,...]
DESCRIPTION
The tabs utility displays a series of characters that clear the hardware terminal tab settings then initialises tab stops at specified posi-
tions, and optionally adjusts the margin.
In the first synopsis form, the tab stops set depend on the command line options used, and may be one of the predefined formats or at regular
intervals.
In the second synopsis form, tab stops are set at positions n1, n2, etc. If a position is preceded by a '+', it is relative to the previous
position set. No more than 20 positions may be specified.
If no tab stops are specified, the ``standard'' UNIX tab width of 8 is used.
The options are as follows:
-n Set a tab stop every n columns. If n is 0, the tab stops are cleared but no new ones are set.
-a Assembler format (columns 1, 10, 16, 36, 72).
-a2 Assembler format (columns 1, 10, 16, 40, 72).
-c COBOL normal format (columns 1, 8, 12, 16, 20, 55)
-c2 COBOL compact format (columns 1, 6, 10, 14, 49)
-c3 COBOL compact format (columns 1, 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58, 62, 67).
-f FORTRAN format (columns 1, 7, 11, 15, 19, 23).
-p PL/1 format (columns 1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 53, 57, 61).
-s SNOBOL format (columns 1, 10, 55).
-u Assembler format (columns 1, 12, 20, 44).
+m[n], +[n]
Set an n character left margin, or 10 if n is omitted.
-T type
Output escape sequence for the terminal type type.
ENVIRONMENT
The LANG, LC_ALL, LC_CTYPE and TERM environment variables affect the execution of tabs as described in environ(7).
The -T option overrides the setting of the TERM environment variable. If neither TERM nor the -T option are present, tabs will fail.
EXIT STATUS
The tabs utility exits 0 on success, and >0 if an error occurs.
SEE ALSO expand(1), stty(1), tput(1), unexpand(1), termcap(5)STANDARDS
The tabs utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
A tabs utility appeared in PWB UNIX. This implementation was introduced in FreeBSD 5.0.
BUGS
The current termcap(5) database does not define the 'ML' (set left soft margin) capability for any terminals.
