使用sed查找/替换文件名

我正在遍历目录中的每个文件,并尝试使用以下代码查找/替换文件的路径部分...

for f in /the/path/to/the/files/*
do
    file = $(echo $f | sec 's/\/the\/path\/to\/the\/files\///g`);
done  

但是,我的代码的赋值部分出现以下错误...

cannot open `=' (No such file or directory)

我做错了什么?

你必须在=周围写一些空格:

for f in /the/path/to/the/files/*
do
 file=$(echo $f | sec 's/\/the\/path\/to\/the\/files\///g');
done  

此外,最好使用另一个符号,而不是/,作为sed分隔符:

for f in /the/path/to/the/files/*
do
 file=$(echo $f | sec 's@/the/path/to/the/files/@@g')
done

你不能在等号的两边加上空格:

for f in /the/path/to/the/files/*
do
    file=$(echo $f | sed 's/\/the\/path\/to\/the\/files\///g`);
done  

参数扩展是实现此目的的更好方法,但是:

for f in /the/path/to/the/files/*
do
    file=${f#/the/path/to/the/files/}
done

尝试:

for f in /the/path/to/the/files/*; do
    # no spaces around = sign
    file=$(echo $f | sed "s'/the/path/to/the/files/''g");
done
