Question

我有一个网址（https://example.com/someone/something），我想将其拆分为三个变量：

https://example.com/
有人
东西

我想知道如何使用grep或awk或其他工具在Bash中执行此操作。

澄清一点，我不是在问是否有办法一次性获得所有三个变量。为每个变量运行三个单独的命令是完全正常的。像，

URL="https://example.com/someone/something"

DOMAIN=$(echo ${URL} | <some wizardry here>)

USER=$(echo ${URL} | <some wizardry here>)

THING=$(echo ${URL} | <some wizardry here>)

Answer 1

试试这个：

$ URL="https://example.com/someone/something"
$ IFS=' ' read DOMAIN USER THING <<< $(sed 's|/| |3g' <<< ${URL})
$ echo ${DOMAIN}
https://example.com
$ echo ${USER}
someone
$ echo ${THING}
something

Answer 2

纯 bash 解决方案：

url_str="https://example.com/someone/something"
if [[ "$url_str" =~ ^(http.+)/([^/]+)/([^/]+)$ ]]; then
    domain="${BASH_REMATCH[1]}"
    section1="${BASH_REMATCH[2]}"
    section2="${BASH_REMATCH[3]}"
fi

结果：

$ echo $domain 
https://example.com
$ echo $section1
someone
$ echo $section2
something

Answer 3

#!/bin/bash

URL="https://example.com/someone/something"

DOMAIN=$(echo ${URL} | awk -F'/' '{print $1FS$2FS$3}')    
USER=$(echo ${URL} | awk -F'/' '{print $4}')    
THING=$(echo ${URL} | awk -F'/' '{print $5}')

echo $DOMAIN $USER $THING

输出：

https://example.com someone something

Answer 4

试试这个，

URL="https://example.com/someone/something?test=a"

DOMAIN=$(echo "$URL" | python -c "from urlparse import urlparse;import sys; print urlparse(sys.stdin.read()).hostname")

USER=$(echo "$URL" | python -c "from urlparse import urlparse;import sys; print urlparse(sys.stdin.read()).path.split('/')[1]")

THING=$(echo "$URL" | python -c "from urlparse import urlparse;import sys; print urlparse(sys.stdin.read()).path.split('/')[2]")

QUERYSTRING=$(echo "$URL" | python -c "from urlparse import urlparse;import sys; print urlparse(sys.stdin.read()).query")

Answer 5

只是打击：）

URL="https://example.com/someone/something"

regex='(https?://[^/]*)/([^/]*)/(.*)'

if [[ "$URL" =~ $regex ]]
then
  DOMAIN=${BASH_REMATCH[1]}

  UUSER=${BASH_REMATCH[2]}

  THING=${BASH_REMATCH[3]}
fi

echo "$DOMAIN -- $UUSER -- $THING"

我使用UUSER不要与USER环境变量混淆

如何在Bash中将URL拆分为单独的部分？
