我正在尝试找到在odt文件列表中查找单词的方法。我的意思是odt文件中有一个字。 然后,我想查看哪些文件包含该单词以及与该单词匹配的行(或至少在它之前的某些单词,在其之后的某些单词)。
这是我到目前为止所拥有的:
for file in *.odt; do unzip -c "$file" | grep -iq "searched_word" && echo "$file"; done
这会向我显示包含我要查找的单词的文件的名称:
filename1.odt
filename2.odt
但是,我也无法成功看到与文件中单词匹配的行,例如:
the is the first line with searched_word blabla : /path/filename1.odt
the is the second line with searched_word blabla : /path/filename2.odt
有什么主意吗?

将grep输出读取到变量中,并使用相同的语句回显
grep -i "searched_word" | read x && echo "$x:$file"
$ cat filename1.odt
the is the first line with searched_word blabla
fsds
sdgdf
$ cat filename2.odt
gfdgj gdflgjdfl
the is the second line with searched_word blabla
fdg gdfgdf
$ for file in *.odt; do ; cat $file | grep -i "searched_word" | read x && echo "$x:$file" ; done
the is the first line with searched_word blabla:filename1.odt
the is the second line with searched_word blabla:filename2.odt
否定情况
$ for file in *.odt; do ; cat $file | grep -i "QQQQQ" | read x && echo "$x:$file" ; done
$

一种方法是让grep打印您的文件名,即使您使用的是stdin。有以下选项:
-H, --with-filename
Print the file name for each match. This is the default when there is more than one file to search.
--label=LABEL
Display input actually coming from standard input as input coming from file LABEL. This is especially useful when implementing tools like zgrep, e.g., gzip -cd foo.gz | grep --label=foo -H
something. See also the -H option.
-n, --line-number
Prefix each line of output with the 1-based line number within its input file.
-a, --text
Process a binary file as if it were text; this is equivalent to the --binary-files=text option.
因此,您只需设置--label=$file -Ha -n
即可获得输出,就好像直接运行grep一样。
您需要犯-H ...容易犯的错误,但是如果没有,则会出现“只有1个输入文件”,因此不会打印任何标签。
如果grep的启发式方法确定输入看起来像二进制,则可能需要-a。
实际上,为什么不能直接运行grep?某些grep安装会自动解压缩.gz文件。
