Beschreibung
Das Shell script environment2.sh dient dazu Environment Variablen die in einer Datei definiert sind auszulesen und zu setzen.Achtung:
Dies ist nur ein Beispiel und sollte an die individuellen Bedürfnisse angepaßt werden
Die Konfigurationsdatei sieht wie folgt aus:
#Hostname/Standard #Environment #Variable #----------------------------------------------------------------------- ... STANDARD #SYSTEM_NAME #`hostname` STANDARD #DATE_DAY #`date +%y%m%d` STANDARD #DATE_FILE #`date +%Y%m%d_%H%M%S` STANDARD #LOGDIR #/tmp STANDARD #LOGOWNER #root:sys STANDARD #LOGPERM #644 STANDARD #REPORTLOGFILE #$LOGDIR/`date +%y%m%d`_CCF.log STANDARD #REPORTOWNER #root:sys STANDARD #REPORTPERM #644 STANDARD #TMPFILEDIR #/tmp STANDARD #CONFIGDIR #$COMPANY_BASE/local/etc STANDARD #ORACONFIGDIR #/usr/local/oracle/etc STANDARD #BACKUP_CONFIG #$COMPANY_BASE/`hostname`/etc STANDARD #CLEANUP_AGE #45 STANDARD #FIND_EXCLUDE #"/SD_CDROM" STANDARD #TRUE #1 STANDARD #FALSE #0 STANDARD #RTN_CODE #0 STANDARD #RTN_BORDER #0 STANDARD #MAIL_RECEIVER #"Reinhold.Flecke@XXX.com" ... hpjapp7 #BACKUP_CONFIG #/var/backup/`hostname` hp11itest #BACKUP_CONFIG #/var/backup/`hostname` ... #### IGNITE HPUX Setting: ### ############################# IgniteUX #IGNITE_SERVER #hpjapp7 IgniteUX #IGNITE_CLIENT #`hostname` IgniteUX #IGNITE_ARCHIVE #"nas073:/vol/ignite_ux/q_files/archives/`hostname`/`uname -r`" IgniteUX #IGNITE_N_ARCHIVE #4 IgniteUX #IGNITE_OPTIONS #"-x inc_entire=vg00 -x exclude=/ccfmnt -d `hostname`-`uname -r`-Archive" IgniteUX #IGNITE_TAPE #/dev/rmt/0mn IgniteUX@hp11itest #IGNITE_SERVER #10.16.5.41 IgniteUX@hp11itest #IGNITE_ARCHIVE #"10.16.5.11:/var/opt/ignite/archives/`hostname`/`uname -r`" IgniteUX@hpcapp1 #IGNITE_OPTIONS #"-f /var/opt/ignite/etc/ignite_archive_content_`hostname`" IgniteUX@hpcapp2 #IGNITE_OPTIONS #"-f /var/opt/ignite/etc/ignite_archive_content_`hostname`" IgniteUX@hpjapp8 #IGNITE_SERVER #hp11itest IgniteUX@hpx2660 #IGNITE_SERVER #hp11itest IgniteUX@hpx2660 #IGNITE_OPTIONS #"-f /usr/local/edc/etc/testen" ... #### Tivoli Setting: ######## ############################# TivoliFrmwk #FRMWK_ENTERPRISE #'1.3.6.1.4.1.50' TivoliFrmwk #FRMWK_HOST #'aixhu02' TivoliFrmwk #FRMWK_RED_ALERT #1410 TivoliFrmwk #FRMWK_YELLOW_ALERT #1420 TivoliFrmwk #FRMWK_CLEAR_ALERT #1430 TivoliFrmwk #FRMWK_CALLOUT #"CCF (Reinhold Flecke +49 XXXX XXXXXX)" TivoliFrmwk #FRMWK_CALLINFO #"CCF-HU" TivoliFrmwk #FRMWK_ALERT #"Test Alert.

Anwendung
mit Hilfe der -he Option erhält man Informationen bzgl. der benutzten Optionen.environment2.sh -he
environment2.sh
#-------------
script setting standard definitions
usage: environment2.sh [-he]
usage: environment2.sh [-de] [-ce configfile] [-Fe Projekt]
-he -shows help message for environment.sh
-de -debug display only commands
-ce value -configfile
-Fe value [value2] [value3] ...
-search for specific environment settings
#-----------------------------------------------------------------------
Die -he Option ist ein Sonderfall, aber notwendig, da dieses Script Bestandteil einer Programmierumgebung ist und allein nicht genutzt wird. Die standardäßige -h oder --help Option wird in den eigentlichen Programmen benutzt.
Anbei eine detailiert Beschreibung der einzelnen Optionen:
- -he
ist ein Sonderfall, aber notwendig, da dieses Script Bestandteil einer Programmierumgebung ist und allein nicht genutzt wird. Das gleiche gilt für die -hf Option des function2.sh? scriptes. Die standardäßige -h oder --help Option wird in den eigentlichen Programmen benutzt (siehe auch Shell Programmierung ). - -de
diese Option ist zum debuggen der aus dem configfile ausgelesenen Umgebungsvariablen. - -ce value
kann für spezielle config files gesetzt werden, die nicht auf dem standard PATH
/ccf/[Server]/etc/environment.cfg:/ccf/[OS]/etc/environment.cfg:/ccf/local/etc/environment.cfg
gespeichert sind. - -Fe value [value2] [value3] ...
dies ist der search String der dazu benutzt wird die Umgebungsvariablen aus dem environment.cfg file zu extrahieren.
per default wird STANDARD und der Servername `hostname` benutzt
