rlwrap 的安裝使用（實現sqlplus下命令列history編輯）

rlwrap 的安裝使用

在Windows作業系統上,當在DOS命令視窗中執行SQL*Plus的時候,可以使用向上,向下鍵來跳回之前已經執行過的SQL語句.你可以根據需要修改他們,然後按Enter鍵重新提交執行.
然而,當在Linux Shell中執行SQL*Plus的時候,並不提供瀏覽歷史命令列的功能.
為了在Linux中達到同樣的目的,你可以安裝rlwrap,這個程式本身是個Shell,可以執行任何你提供給它的命令包括引數,並新增命令歷史瀏覽功能.The rlwrap program is under the GPL license.
一:安裝readline
OS的安裝光碟裡提供了readline包.
[root@oracle11g ~]# rpm -Uvh readline*
error: Failed dependencies: libtermcap-devel is needed by readline-devel-5.1-1.1.i386.rpm
[root@oracle11g ~]# rpm -Uvh libtermcap-devel-2.0.8-46.1.i386.rpm
[root@oracle11g ~]# rpm -Uvh readline*
package readline-5.1-1.1 is already installed
[root@oracle11g ~]# rpm -Uvh readline-devel-5.1-1.1.i386.rpm
二:安裝rlwrap
Download：

[root@oracle11g ~]# tar -zxvf rlwrap-0.30.tar.gz
[root@oracle11g ~]# cd rlwrap-0.30
[root@oracle11g rlwrap-0.30]# ./configure
[root@oracle11g rlwrap-0.30]# make
[root@oracle11g rlwrap-0.30]# make install
[root@oracle11g rlwrap-0.30]# rlwrap
Usage: rlwrap [options] command ...
Options:
  -a[password:]              --always-readline[=password:]
  -A                         --ansi-colour-aware

  -i                         --case-insensitive
  -l                   --logfile=
  -n                         --no-warnings
  -p[ANSI colour spec]       --prompt-colour[=ANSI colour spec]
  -P                  --pre-given=
  -q                  --quote-characters=
  -m[newline substitute]     --multi-line[=newline substitute]
  -r                         --remember
  -v                         --version
  -s                      --histsize= (negative: readonly)
  -t                   --set-term-name=
bug reports, suggestions, updates:

[root@oracle11g rlwrap-0.30]# vi /home/oracle/.bash_profile
新增
alias sqlplus='rlwrap sqlplus'
alias rman='rlwrap rman'
三:使用rlwrap
[oracle@oracle11g ~]$ sqlplus / as sysdba
