Doing a find and then greping will certainly find the string within a string (in the file name) and works much better and faster. You are right PxT, this will not search the string within the file.

Code:

find / | grep lib

You will find a zillion occurances of the string 'lib' within a string. Here is a small sample and I've not even refined the grep or egrep (and just captured small output).

/usr/lib/gdk-pixbuf/loaders/libpixbufloader-png.so.1.0.0
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-pnm.a
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-pnm.la
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-pnm.so.1.0.0
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-ras.a
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-ras.la
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-ras.so.1.0.0

/usr/lib/gdk-pixbuf/loaders/libpixbufloader-tiff.la
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-tiff.so.1.0.0
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-xpm.a
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-xpm.la
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-xpm.so.1.0.0
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-bmp.so
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-bmp.so.1
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-gif.so
/usr/lib/gdk-pixbuf/loaders/libpixbufloader-gif.so.1

Yes, it does not search the actual file. I normally use PERL for that and not xargs. For some strange reason, xargs and I don't gel.... when I have to search files and strings within lots of files I use command line PERL.

Grep to ignore suffix & find end of line

In COBOL, a hyphen can be used in a field name and in a specific program some field names would be identical to others except a suffix was added--sometimes a suffix to a suffix was used. For example, assume I am looking for AAA, AAA-BBB, and AAA-BBB-CCC and don't want to look at AAA-BBB-CCC...

NAME

       gdk-pixbuf-csource - C code generation utility for GdkPixbuf images

SYNOPSIS

       gdk-pixbuf-csource [OPTION...] [IMAGE]

       gdk-pixbuf-csource [OPTION...] --build-list [[NAME] [IMAGE]...]

DESCRIPTION

       gdk-pixbuf-csource is a small utility that generates C code containing images, useful for compiling images directly into programs.

       gdk-pixbuf-csource either takes as input one image file name to generate code for, or, using the --build-list option, a list of (name,
       image) pairs to generate code for a list of images into named variables.

OPTIONS

       --stream
	   Generate pixbuf data stream (a single string containing a serialized GdkPixdata structure in network byte order).

       --struct
	   Generate GdkPixdata structure (needs the GdkPixdata structure definition from gdk-pixdata.h).

       --macros
	   Generate *_ROWSTRIDE, *_WIDTH, *_HEIGHT, *_BYTES_PER_PIXEL and *_RLE_PIXEL_DATA or *_PIXEL_DATA macro definitions for the image.

       --rle
	   Enables run-length encoding for the generated pixel data (default).

       --raw
	   Disables run-length encoding for the generated pixel data.

       --extern
	   Generate extern symbols.

       --static
	   Generate static symbols (default).

       --decoder
	   Provide a *_RUN_LENGTH_DECODE(image_buf, rle_data, size, bpp) macro definition to decode run-length encoded image data.

       --name=identifier
	   Specifies the identifier name (prefix) for the generated variables or macros (useful only if --build-list was not specified).

       --build-list
	   Enables (name, image) pair parsing mode.

       -h, --help
	   Print brief help and exit.

       -v, --version
	   Print version and exit.

       --g-fatal-warnings
	   Make warnings fatal (causes the program to abort).

SEE ALSO

       The GdkPixbuf documentation, shipped with the Gtk+ distribution, available from www.gtk.org[1].

BUGS

       The runlength encoder gets out of sync with the pixel boundaries, since it includes the rowstride padding in the encoded stream.
       Furthermore, it generates pixbufs with suboptimal rowstride in some cases.
