Linux 提取不带扩展名的文件basename

我正在尝试使用

find

命令递归列出目录中的所有

pdf

文件：

find -name "*.pdf" > all_pdf.txt

输出正确，如图所示（all_pdf.txt）：

但我的要求是只列出所有文件的

basename

，而不包括其扩展名，如：

c_primer_5th_edition.pdf
C++Complete Reference (3rd Ed.).pdf
Bjarne Stroustrup - The C++ Programming Language(Third Edition).pdf
...

如何通过提供

filename

（在本例中为'all_pdf.txt'）作为

basename

命令的参数来实现这一点。

使用

sed

要从

all_pdf.txt

中的每一行中删除目录名，请使用：

$ sed -e 's|.*/||' all_pdf.txt 
data structures , algorithms and applications in c++ by sartraj sahani.pdf
C++Complete Reference (3rd Ed.).pdf
Bjarne Stroustrup - The C++ Programming Language(Third Edition).pdf
Essential_C++.pdf
[...snip...]

此外，如果要删除文件扩展名，请使用：

$ sed -e 's|.*/||' -e 's|\.pdf$||' all_pdf.txt 
data structures , algorithms and applications in c++ by sartraj sahani
C++Complete Reference (3rd Ed.)
Bjarne Stroustrup - The C++ Programming Language(Third Edition)
Essential_C++
[...snip...]

使用

grep

要同时删除

.pdf

扩展名，请执行以下操作：

$ grep -Po '[^/]*(?=.pdf$)' all_pdf.txt 
data structures , algorithms and applications in c++ by sartraj sahani

$ awk '{sub(/.*\//, ""); sub(/\.pdf$/, "")} 1' all_pdf.txt

使用

awk

要同时删除

.pdf

扩展名，请执行以下操作：

$ grep -Po '[^/]*(?=.pdf$)' all_pdf.txt

$ awk '{sub(/.*\//, ""); sub(/\.pdf$/, "")} 1' all_pdf.txt

术语“扩展名”通常指文件名的尾随部分，紧跟在最后一个

（在本例中为

pdf

）。
