清理TCL列表和输出



您好,我正在开发一个小脚本,该脚本将允许我解析输入中的信息。这是有效的,但我知道有更好的方法来做到这一点。拜托,我正在努力学习[自学成才],所以撕裂我。输入如下:

C7-0-4-U1   36.5 mHz    IN7-0-4-0   567 mHz 00:15:d0:e3:b0:41   online(pt)  10.106.156.129  42.0    -0.5    35.1    -3.0    38.7    0.0E+000    0.0E+000    9   0    12:20:32 AM    rZ5 1

所需输出如下所示:

00:15:D0:E3:B0:41     10.106.156.129
2C:9E:5F:DE:ED:36     10.113.52.11
E4:83:99:6D:57:AD     10.113.45.239
3C:75:4A:9C:7B:92     10.109.238.61

我拥有的代码如下:

#GET INPUT FROM CLIPBOARD
set Input [sh_set clipboard]
#REMOVE ALL EXCESSIVE WHITESPACE
regsub -all {s{3,}} $Input "n" CleanInput
#SET THE INPUT AS LIST
set List [split $CleanInput "n"]
#GET LIST ITEMS
set Cust1 [lindex $List 1]
set Cust2 [lindex $List 2]
set Cust3 [lindex $List 3]
set Cust4 [lindex $List 4]
regexp -all {(?:[[:xdigit:]]{2}([.-:]))(?:[[:xdigit:]]{2}1){4}[[:xdigit:]]{2}} $Cust1 C1MacAddress
regexp -all {10.(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){2}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)} $Cust1 C1IpAddress
regexp -all {(?:[[:xdigit:]]{2}([.-:]))(?:[[:xdigit:]]{2}1){4}[[:xdigit:]]{2}} $Cust2 C2MacAddress
regexp -all {10.(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){2}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)} $Cust2 C2IpAddress
regexp -all {(?:[[:xdigit:]]{2}([.-:]))(?:[[:xdigit:]]{2}1){4}[[:xdigit:]]{2}} $Cust3 C3MacAddress
regexp -all {10.(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){2}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)} $Cust3 C3IpAddress
regexp -all {(?:[[:xdigit:]]{2}([.-:]))(?:[[:xdigit:]]{2}1){4}[[:xdigit:]]{2}} $Cust4 C4MacAddress
regexp -all {10.(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){2}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)} $Cust4 C4IpAddress
return "$C1MacAddresst$C1IpAddressn$C2MacAddresst$C2IpAddressn$C3MacAddresst$C3IpAddressn$C4MacAddresst$C4IpAddress"
这是我

的解决方案:

# read entire file
set fid [open file.txt r]
set txt [read $fid]
close $fid
# split into lines
set lines0 [split $txt n]
# take only non-empty lines
set lines {}
foreach line $lines0 {
    if {[string trim $line] ne ""} {
        lappend lines $line
    }
}
# extract the required data from each line
foreach line $lines {
    set data [regexp -inline {(w{2}:w{2}:w{2}:w{2}:w{2}:w{2})s+S+s+ (d+.d+.d+.d+)} $line]
    foreach {dummy x y} $data {
        puts "$xt$y"
    }
}

我使用的正则表达式搜索六个用冒号分隔的 2 个字符单词的模式,然后是一个空格,后跟一个单词,后跟一个空格 (\s+\S+\s+),然后是 ip 的模式地址。

正则表达式返回一个三重奏列表(这是平面的,而不是列表列表),其中每个三重奏由整个匹配项组成,然后是第一个 parnthesis 匹配项,然后是 scond 匹配项。因此,假变量。

或者,您可以不使用正则表达式,因为每行都有相同数量的单词。由于在 tcl 中,您可以将字符串视为 alist,其项目被空格隔开,因此您可以通过以下方式更简单地提取数据:

foreach line $lines {
    set x [lindex $line 6]
    set y [lindex $line 8]
    puts "$xt$y"
}

好吧,假设我们从 txt 文件加载它,这就是我的做法:

set input [open "file.txt" r]
set output [open "output.txt" w]
set count 1
while {[gets $input line] != -1} {
    if {$line == ""} {continue} #Skip empty lines
    regexp -all {(w{2}:w{2}:w{2}:w{2}:w{2}:w{2})} $line - MacAddress #trap the mac address and store into $MacAddress
    regexp -all {(d+.d+.d+.d+)} $line - IpAddress #trap the IP address and store into $IpAddress
    puts $output "Customer $count: $MacAddress $IpAddress"
    incr count
}
close $input
close $output

我只是觉得,如果你能说出哪个客户是哪个^^,那可能会很花哨。如果您不需要该额外功能,您可以删除"客户$count"部分和任何涉及"$count"的行。

或者,如果输入数据是表格形式(意味着您需要的信息在同一列中,我会选择:

set input [open "file.txt" r]
set output [open "output.txt" w]
set count 1
while {[gets $input line] != -1} {
    if {$line == ""} {continue} #Skip empty lines
    regsub -all { +} $line " " newline #trims excess spaces
    set MacAddress [lindex [split $line " "] 6]
    set MIpAddress [lindex [split $line " "] 8]
    puts $output "Customer $count: $MacAddress $IpAddress"
    incr count
}
close $input
close $output
