我试图从字符串中提取这些匹配项，但它们的位置可能会随着字符串的变化而变化

尝试的代码：

KPAE
KPSC
KPUW
KRNT
KSEA
KSFF
KSHN
KTIW

{"sids": ["24222 1", "452670 2", "PAE 3", "KPAE 5", "USW00024222 6"], "name": "EVERETT SNOHOMISH AP"},
{"sids": ["24163 1", "PSC 3", "KPSC 5", "USW00024163 6"], "name": "PASCO TRI CITIES AP"},
{"sids": ["94129 1", "PUW 3", "KPUW 5", "USW00094129 6"], "name": "PULLMAN MOSCOW RGNL AP"},
{"sids": ["94248 1", "RNT 3", "KRNT 5", "USW00094248 6"], "name": "RENTON MUNI AP"},
{"sids": ["24233 1", "457473 2", "SEA 3", "72793 4", "KSEA 5", "USW00024233 6", "SEA 7"], "name": "SEATTLE TACOMA INTL AP"},
{"sids": ["94176 1", "SFF 3", "KSFF 5", "USW00094176 6"], "name": "SPOKANE FELTS FLD"},
{"sids": ["94227 1", "457585 2", "SHN 3", "KSHN 5", "USW00094227 6", "SHN 7"], "name": "SHELTON SANDERSON FLD"},
{"sids": ["94274 1", "TIW 3", "KTIW 5", "USW00094274 6"], "name": "TACOMA NARROWS AP"},

awk -F',' '{print $5}'

使用

grep-oP

：

grep -Po '"\K[A-Z]{4}\b' file

KPAE
KPSC
KPUW
KRNT
KSEA
KSFF
KSHN
KTIW

你好我怎样才能同时提取所有与

US*

Hi匹配的值呢？很抱歉，缺少信息。。。我还希望提取与以下内容类似的所有值：

USW00024163

然后可以使用：

grep-Po'\bUS\w*|“\K[A-Z]{4}\b'文件

谢谢！我怎样才能得到按以下格式逐行打印的结果？

KPAE，USW00024222

请不要通过注释来扩展问题。您可以这样做：

grep-Po'\bUS\w*|“\K[A-Z]{4}\b'文件| awk-vofs=，'NR%2{p=$1；next}{print p，$1}
