Complete!以上输出表示基于已配置的官方repository此bash已是最新版。实际上5.1这个小版本中最新的是5.1.16。系统认为5.1.8是最新应该是处于稳定性的考虑。因为Bash是核心组件官方通常不会通过 yum update 将其进行升级最多只会推送同一个小版本系列的安全补丁。由于不能自动升级只能下载源码手工安装了。以下安装过程参考 GNU Bash手册 10.1 Basic Installation。目前Bash版本最新为5.3。首先从GNU官网下载Bash源码$wgethttps://ftp.gnu.org/gnu/bash/bash-5.3.tar.gz $ls-lh --time-stylelong-iso total 11M -rw-r--r--.1root root 11M2025-07-3014:07 bash-5.3.tar.gz可以看到源码的日期为25年7月30日大小11M。解压展开后近40M:$tar-zxf bash-5.3.tar.gz $lsbash-5.3 bash-5.3.tar.gz $du-sh bash-5.3 39M bash-5.3然后进入标准的安装过程中间的大量输出省略$cdbash-5.3/# configure 耗时 38秒$ ./coechnfigure# make 耗时1分12秒$make# tests耗时2分10秒报了很多警告但$?仍是0$maketests# install 耗时12秒$makeinstall整个过程不到5分钟还是挺快的。没想到最慢的是下载源码。 默认安装目录为 /usr/local/lib/bash不会覆盖系统的 /bin/bash。查看安装的版本$ /usr/local/bin/bash --version GNU bash, version5.3.0(1)-release(x86_64-pc-linux-gnu)Copyright(C)2025Free Software Foundation, Inc.
