print lines which match multiple patterns
Hi,

I have a text file as follows:
Code:
11:38:11.054 run1_rdseq    avg_2-5 999988.0000  1024.0000   
11:50:52.053 run3_rdrand    999988.0000   1135.0 128.0417   
11:53:18.050 run4_wrrand    avg_2-5 999988.0000  8180.5833
11:55:42.051 run4_wrrand    avg_2-5 999988.0000   213.8333
11:55:06.053 run4_wrrand    999988.0000   9807 510.2083

I have a variable $run, that contains all the unique values of column 2. I need to print lines that match $run and the pattern 'avg'. So from the above text file I would want to print :
Code:
11:38:11.054 run1_rdseq    avg_2-5 999988.0000  1024.0000   
11:53:18.050 run4_wrrand    avg_2-5 999988.0000  8180.5833
11:55:42.051 run4_wrrand    avg_2-5 999988.0000   213.8333

If I do something like :
Code:
egrep -e '(run4_wrrand.*avg)' textfile.txt

, I get the right output. But if I do:
Code:
egrep -e '($run.*avg)' flatfile.html

I get no output. I know shell variables can not be used in this way, but how else can I achieve the above output?


Thanks
Anna

paps

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.
