Full Discussion: Awk: Version && nextfile
Top Forums Shell Programming and Scripting Awk: Version && nextfile Post 45460 by fpmurphy on Sunday 21st of December 2003 06:46:07 PM

The version of awk shipped with HP-UX is POSIX-complient
and I believe essentially a version of the AT&T Toolchest
nawk (new awk).

nawk does not support the nextfile keyword.

nextfile is a specific gawk extension.

See the GNU awk users guide (www.gnu.org) for details
of how to implement nextfile as an awk function. The code
is as follows but you should read the full text to understand
side effects, etc.

# nextfile --- skip remaining records in current file
# correctly handle successive occurrences of the same file
# this should be read in before the "main" awk program

function nextfile() { _abandon_ = FILENAME; next }

_abandon_ == FILENAME {
if (FNR == 1)
_abandon_ = ""
else
next
}

ucblinks(1B)                                         SunOS/BSD Compatibility Package Commands                                         ucblinks(1B)

NAME
ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices SYNOPSIS
/usr/ucb/ucblinks [-e rulebase] [-r rootdir] DESCRIPTION
ucblinks creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi- ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry. ucblinks does not remove unneeded compatibility links; these must be removed by hand. ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been created, since the reconfiguration may have resulted in more compatibility names being needed. In releases prior to SunOS 5.4, ucblinks used a nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses nawk for the default operation, although nawk rule-bases can still be specifed with the -e option. The nawk rule-base equivalent to the SunOS 5.4 default operation can be found in /usr/ucblib/ucblinks.awk. OPTIONS
-e rulebase Specify rulebase as the file containing nawk(1) pattern-action statements. -r rootdir Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /. FILES
