What exactly do you want to do with the three fields?
I just want to take the text file which is full of numbers and passing the values (three at a time) into variables that I will use as arguments to pass into a function within the loop. I just don't know how to iterate through the file three fields/numbers at a time to assign every three numbers to x, y, and z variables. I hope I am making sense...
Can someone tell me how to do this using sed, awk, or any other basic shell scripting? Basically I have two text files with the following contained in each file:
File A:
a b c
d e f
g h i
File B:
1
2
3
I want the final outcome to look like this:
a b c 1
d e f 2
g h i 3

cat foo.txt|while read line

exif
exif(n) EXIF parsing exif(n)
NAME
exif - Tcl EXIF extracts and parses EXIF fields from digital images
SYNOPSIS
package require Tcl 8.2
package require exif ?1.0?
exif::analyze channel
exif::fieldnames
DESCRIPTION
The EXIF package is a recoding of Chris Breeze's Perl package to do the same thing. This version accepts a channel as input and returns a
serialized array with all the recognised fields parsed out.
There is also a function to obtain a list of all possible field names that might be present, which is useful in building GUIs that present
such information.
COMMANDS
exif::analyze channel
channel should be an open file handle rewound to the start. It does not need to be seekable. channel will be set to binary mode
and is left wherever it happens to stop being parsed, usually at the end of the file or the start of the image data. You must open
and close the stream yourself. If no error is thrown, the return value is a serialized array with informative English text about
what was found in the EXIF block. Failure during parsing or I/O throw errors.
exif::fieldnames
This returns a list of all possible field names. That is, the array returned by exif::analyze will not contain keys that are not
listed in the return from exif::fieldnames. Of course, if information is missing in the image file, exif::analyze may not return
all the fields listed in the return from exif::fieldnames. This function is expected to be primarily useful for building GUIs to
display results.
N.B.: Read the implementation of exif::fieldnames before modifying the implementation of exif::analyze.
