awk -F '"' '/version/ {print $2}' 什么意思

这是一个在 Linux 操作系统下使用的 awk 命令，其中 -F '"' 表示使用双引号作为分隔符，/version/ 表示查找包含字符串 version 的行，{print $2} 表示打印该行的第二个字段（即双引号之间的版本号）。

以下shell脚本是什么意思，转成python是什么样的。 if [ 1 -eq $# ] && [ "-V" == "$1" -o "-v" == "$1" ] ; then echo "TU version is:$TU_VERSION" exit 0 fi line_temp=$(cat /root/SLOT_SN.txt | head -1 | awk -F ";" '{print $1}' | grep "-") if [ -n "$line_temp" ] ; then flag=1 fi while read line_temp do if [ "$line_temp" = "" ] ; then continue fi SLOT_INFO[$num]=$(echo $line_temp | awk -F ";" '{print $1}' | tr A-Z a-z | tr -d ":") if [ $flag = 1 ] ; then LINK_ID[$num]=$(echo $line_temp | awk -F ":" '{print $2}' | awk -F ";" '{print $1}' | awk -F "-" '{print $1}' | sed 's/^0*//g') LINK_ID[$num]=$((LINK_ID[$num]+0)) SLOT_ID[$num]=$(echo $line_temp | awk -F ":" '{print $2}' | awk -F ";" '{print $1}' | awk -F "-" '{print $2}' | sed 's/^0*//g') SLOT_ID[$num]=$((SLOT_ID[$num]+0)) else SLOT_ID[$num]=$(echo $line_temp | awk -F ":" '{print $2}' | awk -F ";" '{print $1}' | sed 's/^0*//g') SLOT_ID[$num]=$((SLOT_ID[$num]+0)) fi #获取UUT_SN UUT_SN[$num]=$(echo $line_temp | awk -F ":" '{print $3}' | awk -F ";" '{print $1}') ((num++)) done </root/SLOT_SN.txt

这个shell脚本的主要作用是从/root/SLOT_SN.txt文件中读取数据，将其解析并存储到相应的数组中。

转成python代码可能会像这样：

import os

if len(sys.argv) == 2 and (sys.argv[1] == "-V" or sys.argv[1] == "-v"):
    print("TU version is:{}".format(TU_VERSION))
    exit(0)

with open('/root/SLOT_SN.txt', 'r') as f:
    num = 0
    SLOT_INFO = []
    LINK_ID = []
    SLOT_ID = []
    UUT_SN = []
    flag = 0
    
    line_temp = f.readline().split(';')[0].strip().lower()
    if '-' in line_temp:
        flag = 1
    
    for line in f.readlines():
        line_temp = line.strip()
        if line_temp == "":
            continue
            
        SLOT_INFO.append(line_temp.split(';')[0].lower().replace(':', ''))
        
        if flag == 1:
            link_id = line_temp.split(':')[1].split(';')[0].split('-')[0].lstrip('0')
            LINK_ID.append(int(link_id))
            slot_id = line_temp.split(':')[1].split(';')[0].split('-')[1].lstrip('0')
            SLOT_ID.append(int(slot_id))
        else:
            slot_id = line_temp.split(':')[1].split(';')[0].lstrip('0')
            SLOT_ID.append(int(slot_id))
        
        uut_sn = line_temp.split(':')[2].split(';')[0]
        UUT_SN.append(uut_sn)
        
        num += 1

注意，这只是一种可能的python实现方式，具体实现可能会因为要考虑更多的边界情况而稍有不同。

这是一个 Bash 脚本，用于构建软件包。它包含了两个函数 `build_rpm_package()` 和 `build_deb_package()`，分别用于构建 RPM 和 DEB 类型的软件包。脚本接受一些参数，如架构 `-a`、二进制文件路径 `-b`、操作系统 `-o`、版本号 `-v`、工作目录 `-w`、软件包类型 `-t`、构建 ID `-i`、发布版本号 `-r`、库路径前缀 `-l` 等等。脚本中使用了一些 Linux 命令，如 `mkdir`、`pushd`、`popd`、`rsync`、`sed`、`awk`、`dpkg-shlibdeps`、`dpkg-deb` 等等，用于创建目录、切换工作目录、复制文件、修改文件内容、生成软件包依赖信息等等。脚本最后根据软件包类型调用相应的构建函数，如果类型不是 RPM 或 DEB，则默认同时构建 RPM 和 DEB。
