shell - 如何传递参数并以所需格式输出

问题描述

confirmerror(){
trimline|awk -F ':' '{if($5 != "") print}'
}
result(){
deviceName=$($1|awk '{print $4}')
processId=$($1|awk '{print $5}'|awk -F '[^0-9]*' '{print $2}')
processName=$($1|awk '{print $5}')
description=$($1|awk '{print $6,$7,$8,$9}')
echo $deviceName
echo $processId
echo $processName
echo $description
}
confirmerror | while read line; do result $line; done

函数confirmerror的输出：

May 13 00:01:58 BBAOMACBOOKAIR2 com.apple.xpc.launchd[1] (com.apple.mdworker.bundles[12513]): Could not find uid associated with service: 0: Undefined error: 0 501
May 13 00:01:58 BBAOMACBOOKAIR2 com.apple.xpc.launchd[1] (com.apple.mdworker.bundles[12513]): Service exited with abnormal code: 78
May 13 00:02:12 BBAOMACBOOKAIR2 com.apple.xpc.launchd[1] (com.apple.xpc.launchd.domain.pid.mdmclient.12523): Failed to bootstrap path: path = /usr/libexec/mdmclient, error = 108: Invalid path

需要读取函数x的每一行，经过处理，得到对应的格式输出，上面是我的尝试，但是失败了，所以来求教。

我想要的是：

BBAOMACBOOKAIR2 
1
com.apple.xpc.launchd[1]
(com.apple.mdworker.bundles[12513]): Could not find uid associated with service: 0: Undefined error: 0 501
BBAOMACBOOKAIR2
1
com.apple.xpc.launchd[1]
(com.apple.mdworker.bundles[12513]): Service exited with abnormal code: 78
BBAOMACBOOKAIR2
1
com.apple.xpc.launchd[1]
(com.apple.xpc.launchd.domain.pid.mdmclient.12523): Failed to bootstrap path: path = /usr/libexec/mdmclient, error = 108: Invalid path

解决方案

我认为，对于这项工作来说太复杂了。你有 awk，所以用它来完成工作。

文件：error.awk

{
    gsub(/^ */, "", $0)
    gsub(/ *$/, "", $0)
    FS = ":"
    if ($5 == "") {
        next
    }
}
{
    FS = " "
    deviceName = $4
    processId = $5
    gsub(/^.*\[/, "", processId)
    gsub(/\].*$/, "", processId)
    processName = $5
    $1 = $2 = $3 = $4 = $5 = ""
    gsub(/^ */, "", $0)
    description = $0
    print deviceName
    print processId
    print processName
    print description
}

并使用它：

output_command_or_cat_filename | awk -f error.awk

输出：

BBAOMACBOOKAIR2
1
com.apple.xpc.launchd[1]
(com.apple.mdworker.bundles[12513]): Could not find uid associated with service: 0: Undefined error: 0 501
BBAOMACBOOKAIR2
1
com.apple.xpc.launchd[1]
(com.apple.mdworker.bundles[12513]): Service exited with abnormal code: 78
BBAOMACBOOKAIR2
1
com.apple.xpc.launchd[1]
(com.apple.xpc.launchd.domain.pid.mdmclient.12523): Failed to bootstrap path: path = /usr/libexec/mdmclient, error = 108: Invalid path
