Both commands run great, my actual dataset is
~960,000 lines or 26 MB. Is there a more efficient way to search this file? The two file formats are as posted, they are just quite large. Thank you

gdalinfo
gdalinfo(1) General Commands Manual gdalinfo(1)
NAME
gdalinfo - gdalinfo lists information about a raster dataset
SYNOPSIS
gdalinfo [--help-general] [-mm] [-stats] [-hist] [-nogcp] [-nomd]
[-noct] [-nofl] [-checksum] [-proj4] [-mdd domain]*
[-sd subdataset] datasetname
DESCRIPTION
The gdalinfo program lists various information about a GDAL supported raster dataset.
-mm
Force computation of the actual min/max values for each band in the dataset.
-stats
Read and display image statistics. Force computation if no statistics are stored in an image.
-hist
Report histogram information for all bands.
-nogcp
Suppress ground control points list printing. It may be useful for datasets with huge amount of GCPs, such as L1B AVHRR or HDF4 MODIS
which contain thousands of them.
-nomd
Suppress metadata printing. Some datasets may contain a lot of metadata strings.
-noct
Suppress printing of color table.
-checksum
Force computation of the checksum for each band in the dataset.
-mdd domain
Report metadata for the specified domain
-nofl
(GDAL >= 1.9.0) Only display the first file of the file list.
-sd subdataset
(GDAL >= 1.9.0) If the input dataset contains several subdatasets read and display a subdataset with specified number (starting from
1). This is an alternative of giving the full subdataset name.
-proj4
(GDAL >= 1.9.0) Report a PROJ.4 string corresponding to the file's coordinate system.
The gdalinfo will report all of the following (if known):
o The format driver used to access the file.
o Raster size (in pixels and lines).
o The coordinate system for the file (in OGC WKT).
o The geotransform associated with the file (rotational coefficients are currently not reported).
o Corner coordinates in georeferenced, and if possible lat/long based on the full geotransform (but not GCPs).
o Ground control points.
o File wide (including subdatasets) metadata.
o Band data types.
o Band color interpretations.
o Band block size.
o Band descriptions.
o Band min/max values (internally known and possibly computed).
o Band checksum (if computation asked).
o Band NODATA value.
o Band overview resolutions available.
o Band unit type (i.e.. 'meters' or 'feet' for elevation bands).
o Band pseudo-color tables.
