Linux basename命令的使用方法

Linux basename命令的使用方法

在Linux系统中，basename命令是一个非常实用的工具，它可以帮助我们从文件路径中提取文件名，本文将详细介绍basename命令的使用方法，以及一些实际应用场景。

1、basename命令的基本用法

basename命令的基本用法非常简单，只需要在命令行中输入basename，后面跟上一个文件路径作为参数，就可以得到该文件路径中的文件名。

basename /home/user/documents/file.txt

执行上述命令后，将输出：

file.txt

2、提取目录中的文件名

我们需要从一个包含多个文件的目录中提取所有文件的文件名，这时，我们可以使用通配符*来匹配目录中的所有文件，然后使用basename命令提取文件名。

basename /home/user/documents/*.txt

执行上述命令后，将输出目录/home/user/documents/中所有.txt文件的文件名。

3、提取路径中的目录名

与提取文件名类似，我们也可以使用basename命令提取路径中的目录名。

basename /home/user/documents/file.txt /home/user/documents/

执行上述命令后，将输出：

documents

4、提取相对路径中的文件名或目录名

我们需要从一个相对路径中提取文件名或目录名，这时，我们可以使用basename命令结合pwd命令来实现。

basename $(pwd)

执行上述命令后，将输出当前工作目录下的文件名或目录名。

5、提取URL中的文件名或目录名

在处理URL时，我们也可以借助basename命令提取文件名或目录名。

echo "https://example.com/path/to/file.txt" | basename -a -s / -d . -p -x -f -v -z -e -q -o -u -h -i -c -l -m -n -k -r -w -t -y -g -j -b -d -A -B -C -D -E -F -G -H -I -J -K -L -M -N -O -P -Q -R -S -T -U -V -W -X -Y -Z -"-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" "-" -"" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" -"/path/to/file.txt" | basename -a -s / -d . -p -x -f -v -z -e -q -o -u -h -i -c -l -m -n -k -r -w -t -y -g -j -b -basename "$(pwd)" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")" | basename -"$(basename "$(pwd)")"` | basen
