[root@openguess rlwrap]# ./configure -q
Will rlwrap find command's working directory under /proc/<commands pid>/cwd? let's see...

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

```
注意linux7 最小安装会报
checking for tgetent in -ltermcap... no
configure: WARNING: No termcap nor curses library found
checking for readline in -lreadline... no
configure: error:
You need the GNU readline library(ftp://ftp.gnu.org/gnu/readline/ ) to build
this program!

```
需要yum install readline-devel -y 就可以

```
make && make install
```
