Oraklet

Et av mine favorittprogram er rlwrap. Det programmet “pakker” jeg inn i andre programmer hvor jeg ønsker at pil-tastene skal anvendes for enkel redigering av teksten.

Hvis du arbeider på Ubuntu Linux finnes pakken ferdig kompilert, da er det bare å laste ned programmet:

 
oracle@ubuntu: ~ $ sudo apt-get install rlwrap
...

For de fleste andre Linux og Unix varianter må du først søke på Google etter rlwrap og laste ned kildekoden.

 
[oracle@linux tmp]$ tar xvzf rlwrap-0.30.tar.gz
rlwrap-0.30/
rlwrap-0.30/completions/
rlwrap-0.30/completions/ftp
...

[oracle@linux tmp]$ cd rlwrap-0.30
/tmp/rlwrap-0.30

[oracle@linux rlwrap-0.30]$ ./configure
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk

...

config.status: creating distribution/rlwrap.spec
config.status: creating config.h
config.status: executing depfiles commands

Now do:
make (or gmake)  to build rlwrap
make check       for instructions how to test it
make install     to install it

[oracle@linux rlwrap-0.30]$ which rlwrap
/usr/local/bin/rlwrap

Muligens må du laste ned fler biblioteker for å få rlwrap til å kompilere.

 
[oracle@linux tmp]$ tar xvzf readline-5.2.tar.gz
readline-5.2/
readline-5.2/doc/
readline-5.2/doc/Makefile.in

...

[oracle@linux readline-5.2]$ cd readline-5.2
/tmp/readline-5.2

[oracle@linux readline-5.2]$  ./configure
[oracle@linux readline-5.2]$ make
[oracle@linux readline-5.2]$ sudo make install
[oracle@linux readline-5.2]$ sudo ldconfig

Legg inn noen alias i for eksempel .bashrc så er rlwrap inkludert i de programmene du bruker hver dag.

 
ingemar@linux: ~ $ cd

ingemar@linux: ~ $ vi .bashrc

alias sql='sqlplus "/ as sysdba"'
alias sqlplus='rlwrap sqlplus'
alias rman='rlwrap rman'
alias dgmgrl='rlwrap dgmgrl'

alias boston='. ~/.boston'
alias chicago='. ~/.chicago'
alias emrep='. ~/.emrep'

alias test10g='. ~/.test10g'
alias test11g='. ~/.test11g'

alias ll='ls -ltr'

Da er det bare å teste hvordan dine program fungerer.

Lykke til!
