所以基本上我想要的是用户提供三个信息:$1 是文件名 $2 是模式 $3 是更新年份
基本上,我想要做的是找到所有具有企业名称的条目:第一列与模式匹配,并且我只想要那些与 $3 所述特定年份匹配的条目。我还想从匹配的条目中找到以下列:企业名称、描述、地址和更新时间。我有点卡住了,因为当我尝试使用参数提取第一列时,它不起作用??:
sed -E 's/([^,]*),'"$2"'/\1/' "$1"
没有过滤掉任何东西??
答案1
sed
或者awk
两者都是错误的工具。
您的文件是逗号分隔值(CSV)文件,因此最好使用适当的csv
解析器:
csvgrep -c "Business Name" -m "$2" -c "When Updated" -m "$3" "$1"
通过以下方式安装:
sudo apt install csvkit
由于您要过滤的字段恰好是第一个和最后一个,因此您可以使用grep
,awk
或sed
:
awk -F, -v name_pattern="$2" -v year="$3" '$1~name_pattern && $NF~year' "$1"
或者
sed -nE "/[^,]*$2.*$3-[0-9]{2}-[0-9]{2}\$/p" "$1"
或者
grep -P "^[^,]*$2.*$3-[0-9]{2}-[0-9]{2}\$" "$1"
但是请注意,这些解决方案非常脆弱,仅适用于您的简单示例。例如,如果您的企业名称中有逗号,它将不起作用:
"Bla, Bla & sons"
同样,如果您想根据其他字段进行过滤。
csv
应该始终优先考虑合适的解析器!
答案2
默认情况下,sed 不会进行过滤,它会编辑然后打印结果,无论是否进行任何编辑操作。
如果你希望它进行过滤,那么使用选项-n
告诉它在编辑行后不打印它们。然后,你做要打印,请输入 ap 运算符。例如:
sed -nE 's/match string/replace string/p'
然后,只有匹配且成功编辑的内容才会被打印。
但也要意识到,匹配行上任何与匹配字符串不匹配的内容都将完整地通过并打印。因此,如果您只想打印行的某些部分,则匹配字符串必须匹配整行,然后替换字符串只会放回您要打印的部分(当然,除非您确实想打印不匹配的部分)。
