The solution should be a one liner using awk and sed.
Thanks in advance. (5 Replies)

AAA Thing1
BBB Thing2
CCC Thing3
File one is a list of part numbers:
AAA234
BBB678
CCC2345
Is there a sed one-line that would compare a data base with and replace the part numbers so that the output looks like this?
AAA234 Thing1

shtool-install
SHTOOL-INSTALL.TMP(1) GNU Portable Shell Tool SHTOOL-INSTALL.TMP(1)NAME
shtool-install - GNU shtool install(1) command
SYNOPSIS
shtool install [-v|--verbose] [-t|--trace] [-d|--mkdir] [-c|--copy] [-C|--compare-copy] [-s|--strip] [-m|--mode mode] [-o|--owner owner]
[-g|--group group] [-e|--exec sed-cmd] file [file ...] path
DESCRIPTION
This command installs a one or more files to a given target path providing all important options of the BSD install(1) command. The trick
is that the functionality is provided in a portable way.
OPTIONS
The following command line options are available.
-v, --verbose
Display some processing information.
-t, --trace
Enable the output of the essential shell commands which are executed.
-d, --mkdir
To maximize BSD compatiblity, the BSD "shtool "install -d"" usage is internally mapped to the "shtool "mkdir -f -p -m 755"" command.
-c, --copy
Copy the file to the target path. Default is to move.
-C, --compare-copy
Same as -c except if the destination file already exists and is identical to the source file, no installation is done and the target
remains untouched.
-s, --strip
This option strips program executables during the installation, see strip(1). Default is to install verbatim.
-m, --mode mode
The file mode applied to the target, see chmod(1). Setting mode to ""-"" skips this step and leaves the operating system default which
is usually based on umask(1). Some file modes require superuser privileges to be set. Default is 0755.
-o, --owner owner
The file owner name or id applied to the target, see chown(1). This option requires superuser privileges to execute. Default is to skip
this step and leave the operating system default which is usually based on the executing uid or the parent setuid directory.
-g, --group group
The file group name or id applied to the target, see chgrp(1). This option requires superuser privileges to execute to the fullest
extend, otherwise the choice of group is limited on most operating systems. Default is to skip this step and leave the operating
system default which is usually based on the executing gid or the parent setgid directory.
-e, --exec sed-cmd
This option can be used one or multiple times to apply one or more sed(1) commands to the file contents during installation.
EXAMPLE
# Makefile
install:
:
shtool install -c -s -m 4755 foo $(bindir)/
shtool install -c -m 644 foo.man $(mandir)/man1/foo.1
shtool install -c -m 644 -e "s/@p@/$prefix/g" foo.conf $(etcdir)/
HISTORY
The GNU shtool install command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1997 for GNU shtool. It was prompted
by portability issues in the installation procedures of OSSP libraries.
