我试过这个命令,
grep '/static' dir/* | xargs sed -i 's/\/static//g'
但我使用的 sed 版本不支持 -i 参数。
要将文件中的字符串替换为与输出相同的输入文件,我通常这样做:
sed 's/\/static//g' filename.txt > new_filename.txt ; mv new_filename.txt filename.txt
OS X 的版本sed
确实支持-i
,但它需要""
一个参数来告诉它备份文件(或不备份)使用什么文件扩展名。顺便说一句,您只想grep -l
获取文件名。
grep -l '/static' dir/* | xargs sed -i "" 's/\/static//g'
Use perl:
$ perl -pi.bak -e 's@/static@@g' dir/*
You can do this using a loop:
for file in $(grep -l '/static' dir/*) ; do
sed 's/\/static//g' $file > $file.$$ && mv $file.$$ $file
done
I use the .$$
suffix ($$
is the process id of the current shell) to avoid collisions with existing file names, and &&
rather than ;
to avoid clobbering the input file if the sed
command fails for some reason. I also added -l
so grep prints file names rather than matching lines.
Or you can install GNU sed (I'm not sure exactly how to do that on OSX).
