Top Forums Shell Programming and Scripting Find pattern in first field of file Post 302957959 by cjcox on Saturday 17th of October 2015 01:23:27 AM

How about:

Code:
#!/bin/sh

#awkcode=`sed 's,\(.*\),$1 ~ /\1/ { print $0 },' <Pattern.txt`
awkcode=`sed 's,\(.*\),$1 ~ /@\1$/ { print $0 },' <Pattern.txt`

awk "
$awkcode
" <Content.txt

Notice my awkcode line assumes the pattern to match is preceded by @ and must match to end of field. Take a look at the commented out awkcode line if it should match just on the name regardless of where located.

Using the commented out one, the following lines would match for Masters:

Code:
8@XXXXXXXX@Masters @@@@ blah masters
8@XXXXXXXX@McMasters @@@@ blah mcmasters

Warning, my quickie solution assumes that the Patterns are pretty simple and do not contain weird characters that might mess up awk.

pkgproto(1)							   User Commands						       pkgproto(1)

NAME
pkgproto - generate prototype file entries for input to pkgmk command SYNOPSIS
pkgproto [-i] [-c class] [path1] pkgproto [-i] [-c class] [path1=path2...] DESCRIPTION
pkgproto scans the indicated paths and generates prototype(4) file entries that may be used as input to the pkgmk(1) command. If no paths are specified on the command line, standard input is assumed to be a list of paths. If the pathname listed on the command line is a directory, the contents of the directory is searched. However, if input is read from stdin, a directory specified as a pathname will not be searched. OPTIONS
-i Ignores symbolic links and records the paths as ftype=f (a file) versus ftype=s (symbolic link). -c class Maps the class of all paths to class. OPERANDS
path1 Pathname where objects are located. path2 Pathname which should be substituted on output for path1. EXAMPLES
Example 1: Examples of the use of pkgproto.1. The following two examples show uses of pkgproto and a partial listing of the output produced. Example 1: example% pkgproto /bin=bin /usr/bin=usrbin /etc=etc f none bin/sed=/bin/sed 0775 bin bin f none bin/sh=/bin/sh 0755 bin daemon f none bin/sort=/bin/sort 0755 bin bin f none usrbin/sdb=/usr/bin/sdb 0775 bin bin f none usrbin/shl=/usr/bin/shl 4755 bin bin d none etc/master.d 0755 root daemon f none etc/master.d/kernel=/etc/master.d/kernel 0644 root daemon f none etc/rc=/etc/rc 0744 root daemon Example 2: example% find / -type d -print | pkgproto d none / 755 root root d none /bin 755 bin bin d none /usr 755 root root d none /usr/bin 775 bin bin d none /etc 755 root root d none /tmp 777 root root EXIT STATUS
0 Successful completion. >0 An error occurred. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
pkgmk(1), pkgparam(1), pkgtrans(1), prototype(4), attributes(5) Application Packaging Developer's Guide NOTES
By default, pkgproto creates symbolic link entries for any symbolic link encountered (ftype=s). When you use the -i option, pkgproto cre- ates a file entry for symbolic links (ftype=f). The prototype(4) file would have to be edited to assign such file types as v (volatile), e (editable), or x (exclusive directory). pkgproto detects linked files. If multiple files are linked together, the first path encountered is considered the source of the link. By default, pkgproto prints prototype entries on the standard output. However, the output should be saved in a file (named Prototype or prototype, for convenience) to be used as input to the pkgmk(1) command. SunOS 5.10 6 Nov 2000 pkgproto(1)
