如何使用Linux命令跳过字符串开头和结尾的表达式

sh GetPrivateKey appname返回低于输出

我想将其格式化为私钥。所以我写了下面的命令，它在上面的输出中找到空格("(并逐行显示，但我不想拆分-----BEGIN RSA PRIVATE KEY-----和-----END RSA PRIVATE KEY-----(包括它们末尾的空格(

[user@server]$ echo `sh GetPrivateKey appname` | tr " " "n"

我认为sed命令满足了我的需求，但我对Linux命令还很陌生。我们将感谢您的帮助。

预期输出：

您可以尝试此gnu awk:

awk -v RS='-{5}(BEGIN|END) [^-]* KEY-{5}' '{
gsub(/ /, "n"); ORS=RT} 1' file.rsa

或使用perl:

perl -pe 's/-{5}(BEGIN|END) [^-]* KEY-{5}(*SKIP)(*F)|h/n/g' file.rsa

输出：

根据您显示的示例，您可以尝试以下用GNUawk编写的内容吗。

awk '
match($0,/KEY-+.*-+END/){
val=substr($0,RSTART,RLENGTH)
num=split(val,arr," ")
print substr($0,1,RSTART-1) arr[1]
for(i=2;i<num;i++){
print arr[i]
}
print arr[num] substr($0,RSTART+RLENGTH)
}
' Input_file

解释：添加以上详细解释。

awk '                                        ##Starting awk program from here.
match($0,/KEY-+.*-+END/){                    ##Using match function to match regex KEY-+.*-+END in current line.
val=substr($0,RSTART,RLENGTH)              ##Creating val which has sub string of matched regex.
num=split(val,arr," ")                     ##Splitting val into array arr.
print substr($0,1,RSTART-1) arr[1]         ##printing sub string before matched regex character and printing array 1st element.
for(i=2;i<num;i++){                        ##Going through all elements of arr here.
print arr[i]                            ##Printing arr element with index i here.
}
print arr[num] substr($0,RSTART+RLENGTH)   ##Printing rest of line after matched regex.
}
' Input_file

使用任何awk:

$ awk -v OFS='n' '{
beg = end = $0
sub(/- .*/,"-",beg)
sub(/.* -/,"-",end)
gsub(/^.*- | -.*$/,"")
$1 = $1
print beg, $0, end
}' file
