更新:修复了脚本中的错字:更改print $NF
为print $3
;还整理了一下内容,并添加了一些评论。
假设文件名不包含\n
,则以下内容将打印出一个排序后的列表,该列表在unique ,unique 处中断(如:section control breaks),并显示相应的文件路径组。 file name
md5sum
#!/bin/bash
# Choose which script to use for the final awk step
out_script=out_all
# Print all duplicated file names, even when md5sum is the same
out_all='{ if( p1 != $1 ) { print nl $1; print I $2 }
else if( p2 != $2 ) { print I $2 }
print I I $3; p1=$1; p2=$2; nl="\n" }
END { printf nl}'
# Print only duplicated file names which have multiple md5sums.
out_only='{ if( p1 != $1 ) { if( multi ) { print pend }
multi=0; pend=$1 "\n" I $2 "\n" }
else if( p2 != $2 ) { multi++; pend=pend I $2 "\n" }
pend=pend I I $3 "\n"; p1=$1; p2=$2 }
END { if( multi ) print pend }'
# The main pipeline
find "${1:-.}" -type f -name '*' | # awk for duplicate names
awk -F/ '{ if( name[$NF] ) { dname[$NF]++ }
name[$NF]=name[$NF] $0 "\n" }
END { for( d in dname ) { printf name[d] }
}' | # standard md5sum output
xargs -d'\n' md5sum | # " "==text, "*"==binary
sed 's/ [ *]/\x00/' | # prefix with file name
awk -F/ '{ print $3 "\x00" $0 }' | # sort by name. md5sum, path
sort | # awk to print result
awk -F"\x00" -v"I= " "${!out_script}"
输出仅显示带有多个 md5
s的文件名
