这些命令在Mac OS X自带的默认sed中不起作用。

来自男人1 sed:

-i extension
             Edit files in-place, saving backups with the specified
             extension.  If a zero-length extension is given, no backup 
             will be saved.  It is not recommended to give a zero-length
             extension when in-place editing files, as you risk corruption
             or partial content in situations where disk space is exhausted, etc.

试着

sed -i '.bak' 's/old/new/g' logfile*

and

for i in logfile*; do sed -i '.bak' 's/old/new/g' $i; done

两者都工作得很好。

@PaulR将此作为评论发布，但人们应该将其视为一个答案(这个答案最符合我的需求):

sed -i 's/abc/xyz/g' xa*

这将适用于中等数量的文件，可能是几十个，但可能不是几百万个。

您可以同时使用grep和sed。这允许您递归地搜索子目录。

Linux: grep -r -l <old> * | xargs sed -i 's/<old>/<new>/g'
OS X: grep -r -l <old> * | xargs sed -i '' 's/<old>/<new>/g'

For grep:
    -r recursively searches subdirectories 
    -l prints file names that contain matches
For sed:
    -i extension (Note: An argument needs to be provided on OS X)

如果你能够运行一个脚本，下面是我对类似情况所做的:

使用字典/hashMap(关联数组)和sed命令的变量，我们可以遍历数组来替换几个字符串。在name_pattern中包含一个通配符将允许在指定目录(source_dir)中替换文件中的模式(这可能是类似name_pattern='File*.txt')。 所有更改都写在destin_dir的日志文件中

#!/bin/bash
source_dir=source_path
destin_dir=destin_path
logfile='sedOutput.txt'
name_pattern='File.txt'

echo "--Begin $(date)--" | tee -a $destin_dir/$logfile
echo "Source_DIR=$source_dir destin_DIR=$destin_dir "

declare -A pairs=( 
    ['WHAT1']='FOR1'
    ['OTHER_string_to replace']='string replaced'
)

for i in "${!pairs[@]}"; do
    j=${pairs[$i]}
    echo "[$i]=$j"
    replace_what=$i
    replace_for=$j
    echo " "
    echo "Replace: $replace_what for: $replace_for"
    find $source_dir -name $name_pattern | xargs sed -i "s/$replace_what/$replace_for/g" 
    find $source_dir -name $name_pattern | xargs -I{} grep -n "$replace_for" {} /dev/null | tee -a $destin_dir/$logfile
done

echo " "
echo "----End $(date)---" | tee -a $destin_dir/$logfile

First, the pairs array is declared, each pair is a replacement string, then WHAT1 will be replaced for FOR1 and OTHER_string_to replace will be replaced for string replaced in the file File.txt. In the loop the array is read, the first member of the pair is retrieved as replace_what=$i and the second as replace_for=$j. The find command searches in the directory the filename (that may contain a wildcard) and the sed -i command replaces in the same file(s) what was previously defined. Finally I added a grep redirected to the logfile to log the changes made in the file(s).

这在GNU Bash 4.3 sed 4.2.2中为我工作，并基于VasyaNovikov对Bash中元组循环的回答。

更好的是:

for i in xa*; do
    sed -i 's/asd/dfg/g' $i
done

因为没有人知道有多少文件，而且很容易打破命令行限制。

下面是当文件太多时会发生的情况:

# grep -c aaa *
-bash: /bin/grep: Argument list too long
# for i in *; do grep -c aaa $i; done
0
... (output skipped)
#
