使用awk或sed将管道定界符替换为空格
[英]replace a pipe delimiter with a space using awk or sed
问题描述
I have a pipe delimited file with a sample lines like below; 
我有一个用管道分隔的文件，带有下面的示例行；
/u/chaintrk/bri/sh/picklist_autoprint.sh|-rwxrwxr-x|bdr|bdr|2665|Oct|23|14:04|3919089454
/u/chaintrk/bri/sh/generate_ct2020.pl|-rwxrwxr-x|bdr|bdr|15916|Oct|23|14:04|957147508
is there a way that awk or sed can transform the lines into the output like below where the pipe between the month and the date was replaced by space? awk或sed是否有办法将行转换为输出，如下所示，其中月份和日期之间的管道被空格替换了？
/u/chaintrk/bri/sh/picklist_autoprint.sh|-rwxrwxr-x|bdr|bdr|2665|Oct 23|14:04|3919089454
/u/chaintrk/bri/sh/generate_ct2020.pl|-rwxrwxr-x|bdr|bdr|15916|Oct 23|14:04|957147508

With GNU sed: 使用GNU sed：
sed -E 's/(\|[A-Z][a-z]{2})\|([0-9]{1,2}\|)/\1 \2/' file
Output: 输出：
/u/chaintrk/bri/sh/picklist_autoprint.sh|-rwxrwxr-x|bdr|bdr|2665|Oct 23|14:04|3919089454 /u/chaintrk/bri/sh/generate_ct2020.pl|-rwxrwxr-x|bdr|bdr|15916|Oct 23|14:04|957147508
If you want to edit file "in place" add sed's option -i . 如果要“就地”编辑文件，请添加sed的选项-i 。

Yes, it is possible to change a "|" 是的，可以更改“ |” with an space. 与空间。
The real problem is to identify which of the field(s) to change. 真正的问题是确定要更改哪个字段。
Are those always the 6th and 7th? 那些总是第六和第七吗？ If so, this works: 如果是这样，这可行：
awk -vFS='|' '{sub($6"|"$7,$6" "$7)}1' file
Are those with a text Upper-lower-lower followed by a 1 or 2 digits ? 那些文本的Upper-lower-lower后跟1 or 2 digits吗？ If so, this other works: 如果是这样，其他工作原理：
gawk '{c="[|]([[:upper:]][[:lower:]]{2})[|]([0-9]{1,2})[|]";print gensub(c,"|\\1 \\2|",1,$0)}' file
