Didn t 第一次正确地阅读了这个问题。 你们需要一名能够干.或 com的野外分离者。 如果你能够将干ash用作产出现场分离器(因为它是最常见的),并用分类ake:
awk -F ,|- OFS="-" {print $1 "," $4,$3,$2} file
Pure awk
awk -F"," { n=split($2,b,"-");$2=b[3]"-"b[2]"-"b[1];$i=$1","$2 } 1 file
ed
ed -r s/(^.[^,]*,)([0-9]{2})-([0-9]{2})-([0-9]{4})/14-3-2/ file
ed s/(^.[^,]*,)([0-9][0-9])-([0-9][0-9])-([0-9]+)/14-3-2/ file
Bash
#!/bin/bash
while IFS="," read -r a b
do
IFS="-"
set -- $b
echo "$a,$3-$2-$1"
done <"file"
不幸的是,我认为标准<代码>wk只允许一种外地分离特性,因此,必须先处理数据。 您可以通过<代码>tr<>/code>做到这一点,但如果您真的想要awk
,则仅使用:
pax> echo 123,01-08-2006
124,01-09-2007
125,01-10-2009
126,01-12-2010 | awk -F, {print $1"-"$2} | awk -F- {print $1","$4"-"$3"-"$2}
产出:
123,2006-08-01
124,2007-09-01
125,2009-10-01
126,2010-12-01
视需要而定。
第1条<代码>wk 更改<代码>, natures to -
,使您拥有四个与同一性质的领域(通常使用<代码>、>)。
第二张<代码>awk按你规定的顺序打印,同时更正外地离职人员。
如果您重新使用<代码>awk执行,允许采用多个<代码>FS。 品格
gawk -F ,|- {print $1","$4"-"$3"-"$2}
如果不需要k,你也可以使用伯尔语:
$ perl -nle print "$1,$4-$3-$2" while (/(d{3}),(d{2})-(d{2})-(d{4})s*/g) < file.txt
