Parsing hddtemp input

I agree that awk is the tool for this.
It will handle changes in the length of disk names, etc.
better than some other approaches.

Assuming that more than one disk temp is on each input line,
this does something like what you seem to want.
It assumes that the right number of fields will always be provided after the disk name.

Code:
devs="/dev/sda /dev/sdb /dev/sdc"

nc localhost 7634  | nawk -F '|' -v devs="$devs"  '
NR ==1 { ndev = split(devs,dev," ") ; if (ndev < 1) exit(1) }

{
        for (i = 1 ; i <= NF; i++) {
                for (d = 1; d <= ndev; d++) {
                        if ($i == dev[d])
                                print dev[d],$(i+2);
                }
        }
}'  -

/dev/sda 31
/dev/sdb 31
/dev/sdc 36

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. SEE ALSO
shtool(1), umask(1), chmod(1), chown(1), chgrp(1), strip(1), sed(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-INSTALL.TMP(1)
