When I type a command at the command line it supplies one result and the exact same command in a script
egrep '^01|^02|^03|^04' file > fileout
count = 29353
same count in the script yields a count of 23492
is there any reason this could be happening. (1 Reply)

pfsinexr
pfsinexr(1) General Commands Manual pfsinexr(1) NAME
pfsinexr - Load images or frames in OpenEXR format SYNOPSIS
pfsinexr [--keep-rgb] (<file> [--frames <range>] [--skip-missing]) [<file>...] DESCRIPTION
Use this command to read frames in OpenEXR format. The frames are converted to pfs stream and send to the standard output. This command can read arbitrary channels from OpenEXR files; color channels XYZ are however specially handled (see option keep-rgb). pfsinexr reads also all string attributes from OpenEXR file and write them as tags in pfs stream. Attributes of other types are ignored. If attribute name contains a colon (:), the part before colon is treated as a channel name and the attribute is assigned to that channel (sim- ilar notation as command line argument of pfstag program). pfsinexr recognizes OpenEXR standard attribute WhiteLuminance and multiplies the data by that value to get absolute luminance values (see also --fix-halfmax switch in pfsoutexr). Additionally the tag LUMINANCE is set to ABSOLUTE unless OpenEXR files contains attribute LUMI- NANCE set to semething else. That is the channel Y is assumued to represent absolute luminance levels in cd/m^2. If an OpenEXR file contains 'Z' channel, it is renamed to 'DEPTH' to avoid conflict with the Z color channel for the XYZ color space. Details on the format of the pattern file names, which are used for reading multiple frames, can be found in the manual page of pfsinppm. To automatically recognize a file format from the extension, use pfsin command instead. --keep-rgb By default, color channels R, G and B from an OpenEXR file are converted to XYZ color space, which is suggested format for color data in pfs. When keep-rgb option is specified, color channels RGB are stored as they are without any conversion. EXAMPLES
pfsin memorial.exr | pfsout memorial.hdr Converts from one HDR format to another BUGS
pfsinexr and pfsoutexr can not take stdin / stdout as an input/output (dash '-' instead of file name). Please report bugs and comments on implementation to the discussion group http://groups.google.com/group/pfstools SEE ALSO
