Print lines that do not match the pattern
I need to print the lines that do not match a pattern. I tried using grep -v and sed -n '/pattern/!p', but both of them are not working as I am passing the pattern as variable and it can be null some times.

Example

Code:
........ abcd[1234]......
.........abcd[2341]......
.........abcd[1234]......
.........abcd[4567]......
.........abcd[9876]......



would need the output to be not matching pattern 1234, so it would be

Code:
.........abcd[2341]......
.........abcd[4567]......
.........abcd[9876]......


The value in the brackets is passed as a variable and sometimes it can be null
so the grep or sed is not returning any value. when it is supposed to.

Please help.

mdbfontsize

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME

       mdbFontSize - Font Size

DESCRIPTION

       In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a
       bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information
       about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format.

       FONT-SIZE-ADJUSTMENT ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ADJUST-RATIO ::= INTEGER

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT:

	   ((devanagari-cdac) 150)

       instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is
       'devanagari-cdac'.
