传递目录模式作为参数来更改目录的解决方案

我希望获得任何脚本或 Linux 解决方案来实现更改目录，不完全传递目录，而是传递模式作为参数。像这样的东西：

# Ex: I'd like to execute a "cd" to a directory with script as a part of it name. 
# My choice will be 4, so the script will execute cd /usr/share/doc/xorg-scripts-1.0.1

rexcd script

1) /home/prpe/scripts
2) /home/prpe/sintaxe/scripts_plone
3) /home/prpe/sintaxe/scripts_plone/scripts
4) /usr/share/doc/xorg-scripts-1.0.1
5) /usr/x86_64-pc-cygwin/lib/ldscripts

Option [1] 4

prpe@DESK-00-090117 /usr/share/doc/xorg-scripts-1.0.1
$

如果目录模式仅产生一个目录，则解决方案将对该目录执行 cd 命令。

感谢您提供任何解决方案或想法来实施它。

答案1

我想这个功能是你想要完成的吗？

rexcd () {
    search_base=/path/to/base
    pattern=$@

    directories=( $(find "$search_base" -type d -name "*${pattern}*" 2>/dev/null) )

    PS3="Which directory should we change to? "
    select dir in "${directories[@]}"; do
        case $dir in
            *) cd "$dir";break;;
        esac
    done
}

请注意，无论如何，在我的机器上，如果您搜索常用单词，这将显示很多您不想要的内容，具体取决于您的搜索基础的广泛程度。

正在使用：

$ rexcd someweirddir && pwd
1) /Users/jessebutryn/tmp/someweirddir1
2) /Users/jessebutryn/tmp/someweirddir2
Which directory should we change to? 2
/Users/jessebutryn/tmp/someweirddir2

答案2

您正在寻找使用以下select语句：

select dir in /place1 /other/place /path/to/elsewhere; do cd "$dir"; break; done

在收集并加入所有想法/建议后，我构建了这个脚本。标题部分解释了如何使用它以及对新开关的建议。快完成了:)

# * File       : rexcd.sh
# * Goal       : improve cd linux command
# * Requisites :
# *     1. SHELL=bash
# *     2. Locate service available and up to date. It's necessary to search directories

#
# How to use
#
# 1. put this script into a directory (Ex: ~/scripts)
#
# 2. insert this code in your ~/.bashrc:
# . ~/scripts/rexcd.sh
#
# 3. open a new shell session and test it:
# cd ~
# rexcd scripts
#
# 4. Example of output (cygwin 2.10.x)
# Choose one directory
# 
# 1) /home/prpe/scripts
# 2) /home/prpe/sintaxe/scripts_plone
# 3) /home/prpe/sintaxe/scripts_plone/scripts
# 4) /usr/share/doc/xorg-scripts-1.0.1
# 5) /usr/x86_64-pc-cygwin/lib/ldscripts
# Option [1] 2

#
# ToDo:
#
# 1. switch:-i (ignore case)
# 2. switch:-l limits of directories in menu (from m-th to n-th search matches)  (m,n|m,|,n default 1 to number of matches)
# 3. switch:-d root directory -d <dir> (default /)
# 4. switch:-u perform an update of locatedb table
