Search for a word in file and output to another
Hello Experts!

I am trying to perform a common task, searching data from within a file and placing what is found into another.However, I have not been able to figure the “How to” with this situation.

I need to search through all lines within this text and pull the first positional attributes and their formats

For example, I have this line in the file:
Code:
LOGS MEAS FROM=(TABLE=INFO,FORMAT=A25,DESCRIPTION=Point from which logs are measured,ABBREV=LMF,STORAGE FORMAT=F10.3,MIRROR=YES)

I need to pick from this line the following and output to another file:
Code:
LOGS MEAS FROM     FORMAT=A25     FORMAT=F10.3

Because this is a very large file, I am also asking for your help to make this an efficient command.

Many Thanks for Your Help!
Lee

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.
