试试下面的shell命令:

find ./  -type f -name "file*.txt" | xargs sed -i -e 's/abc/xyz/g'

我在其他帖子中发现了这个帖子，我认为它包含了最完整的答案，所以我也添加了我的答案:

sed and ed are so useful...by hand. Look at this code from @Johnny: sed -i -e 's/abc/XYZ/g' /tmp/file.txt When my restriction is to use it in a shell script, no variable can be used inside in place of "abc" or "XYZ". The BashFAQ seems to agree with what I understand at least. So, I can't use: x='abc' y='XYZ' sed -i -e 's/$x/$y/g' /tmp/file.txt #or, sed -i -e "s/$x/$y/g" /tmp/file.txt but, what can we do? As, @Johnny said use a while read... but, unfortunately that's not the end of the story. The following worked well with me: #edit user's virtual domain result= #if nullglob is set then, unset it temporarily is_nullglob=$( shopt -s | egrep -i '*nullglob' ) if [[ is_nullglob ]]; then shopt -u nullglob fi while IFS= read -r line; do line="${line//'<servername>'/$server}" line="${line//'<serveralias>'/$alias}" line="${line//'<user>'/$user}" line="${line//'<group>'/$group}" result="$result""$line"'\n' done < $tmp echo -e $result > $tmp #if nullglob was set then, re-enable it if [[ is_nullglob ]]; then shopt -s nullglob fi #move user's virtual domain to Apache 2 domain directory ...... As one can see if nullglob is set then, it behaves strangely when there is a string containing a * as in: <VirtualHost *:80> ServerName www.example.com which becomes <VirtualHost ServerName www.example.com there is no ending angle bracket and Apache2 can't even load. This kind of parsing should be slower than one-hit search and replace but, as you already saw, there are four variables for four different search patterns working out of one parse cycle.

在给定的假设下，我能想到的最合适的解决方案。

您也可以在bash脚本中使用python。我在这里的一些顶级答案上没有太大的成功，并且发现这个不需要循环就能工作:

#!/bin/bash
python
filetosearch = '/home/ubuntu/ip_table.txt'
texttoreplace = 'tcp443'
texttoinsert = 'udp1194'

s = open(filetosearch).read()
s = s.replace(texttoreplace, texttoinsert)
f = open(filetosearch, 'w')
f.write(s)
f.close()
quit()

可以使用rpl命令。例如，你想改变整个php项目的域名。

rpl -ivRpd -x'.php' 'old.domain.name' 'new.domain.name' ./path_to_your_project_folder/  

这不是一个明确的bash的原因，但它是一个非常快速和有用的。：）

要以非交互式方式编辑文件中的文本，需要就地文本编辑器，例如vim。

下面是一个简单的例子，如何从命令行使用它:

vim -esnc '%s/foo/bar/g|:wq' file.txt

这相当于ex editor的@slim answer，基本上是一样的。

这里有一些实际的例子。

在文件中用bar替换文本foo:

ex -s +%s/foo/bar/ge -cwq file.txt

删除多个文件的尾随空格:

ex +'bufdo!%s/\s\+$//e' -cxa *.txt

故障处理(终端卡死):

添加-V1参数以显示详细消息。 强制退出:-cwq!

你也可以使用ed命令进行文件内搜索和替换:

# delete all lines matching foobar 
ed -s test.txt <<< $'g/foobar/d\nw' 

参见“使用ed通过脚本编辑文件”。
