Match string from two files and print line
Hi,
I have been trying to find help with my issue and I'm thinking awk may be able to do it.
I have two files eg
Code:
file1.txt
STRING1    230    400    0.36
STRING2    400    230    -0.13
STRING3    130    349      1

file2.txt

CUFFFLINKS    1   1394    93932   .   +     STRING1
CUFFFLINKS    1   94055   96078   .   +     STRING1
CUFFFLINKS    1   7654    9000   .     +     STRING3
CUFFFLINKS    1   6544    93932   .   +     STRING4

desired.txt
CUFFFLINKS    1   1394    93932   .   +    STRING1
CUFFFLINKS    1   94055   96078   .   +    STRING1
CUFFFLINKS    1   7654    9000   .   +     STRING3

I would like to loop through all entries in column 1 of file 1 and if the string matches any entry in column 7 of file 2 to print out the line of file 2

I have tried:
Code:
awk 'NR == FNR { a[$1]++ } NR != FNR { for (e in a) for (i=1;i<NF;i++) if (e ~ $i) print $0 }' file1.txt file2.txt

but this doesn't seem to work.

My understanding is that NR will only == FNR when the first file is read in so this populates the 'a' array. Then when NR != FNR (eg when the second file is read in) then there is a loop to try to match every element of 'a' and if this matched to print out the line. I can't see how I can get this specific to column 7 in the second file??
I'm a complete beginner so any help would be really appreciated!
Thanks.

ppmtosixel

ppmtosixel(1)						      General Commands Manual						     ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.	The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
	      pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order	of  magni-
	      tude larger than a compressed file and prints much slower.

       -margin
	      If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
	      fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater	than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
