我希望在每个###之间分别提取文本,以便与不同的文件进行比较。需要提取所有对接者图像的所有CVE编号,以便与以前的报告进行比较。文件如下所示。这是一个片段,它有100多行这样的代码。需要通过Shell脚本来完成。帮帮忙吧。

使用GNU awk (我假设您已经或可以使用GNU grep)来匹配第3 arg ():
$ cat tst.awk
match($0,/^###.* ([^:]+):.*/,a) { print "For", a[1] }
match($0,/\[([^]]+)/,a) { print a[1] }
!NF$ awk -f tst.awk file

在显示的示例中,请尝试遵循awk代码。
awk '
/^##/ && match($0,/docker image[[:space:]]+[^:]*/){
split(substr($0,RSTART,RLENGTH),arr1)
print "for "arr1[3]
next
}
match($0,/^\|\[[^]]*/){
print substr($0,RSTART+2,RLENGTH-2)
}
' Input_file说明:添加了对上述awk代码的详细说明。
awk ' ##Starting awk program from here.
/^##/ && match($0,/docker image[[:space:]]+[^:]*/){ ##Checking condition if line starts from ## AND using match function to match regex docker image[[:space:]]+[^:]* to get needed value.
split(substr($0,RSTART,RLENGTH),arr1) ##Splitting matched part in above match function into arr1 array with default delimiter of space here.
print "for "arr1[3] ##Printing string for space arr1 3rd element here

}
match($0,/^\|\[[^]]*/){ ##using match function to match starting |[ till first occurrence of ] here.
print substr($0,RSTART+2,RLENGTH-2) ##printing matched sub string from above regex.
}

使用awk,您可以做到:
awk -v FS=' |[[]|[]]' '/^[#]+/{sub(/:.*$/,"");print "For " $NF} /^\|\[/{print $2} /^$/ {print ""}' file
