sedを使用してキャプチャグループの内容を置き換える正規表現

Have inputs.conf files in multiple directories that needs to match and parse each stanza and modify the index= to index=secure. This are files type in inputs.conf and also do run the script to locate the inputs file in this dir (_GWAS_pr_linux_t1/local/inputs.conf) to modify the index

In the file

    [WinEventLog://Application]
    checkpointInterval = 5
    current_only = 0
    disabled =0 
    start_from = oldest
    index = 

    [WinEventLog://Security]
    checkpointInterval = 5
    current_only = 0
    disabled =0 
    start_from = oldest
    index = 

    [WinEventLog://System]
    checkpointInterval = 5
    current_only = 0
    disabled =0 
    start_from = oldest
    index = 

    [WinEventLog://ForwardedEvents]
    checkpointInterval = 5
    current_only = 0
    disabled =0 
    start_from = oldest
    index = 

    [WinEventLog://Setup]
    checkpointInterval = 5
    current_only = 0
    disabled =0 
    start_from = oldest
    index = 

I tried with the command

    sed -i -e 's/.*(?s)((\[WinEventLog:\/\/Application|Security|System|ForwardedEvents|Setup\]).*?)(?:(?:\r\n){2}) /index=window inputs.conf

to change to `index=window` for the `Application`, `Security`, `System`, `ForwardedEvents` and `Setup` entry.

In the file

    [monitor:///var/log/cron]
    index=
    sourcetype=linux_secure

    [monitor:///var/log/secure]
    index=
    sourcetype=linux_secure

    [monitor:///var/log/messages]
    index=
    sourcetype=linux

    [monitor:///var/log/spooler]
    index = 
    sourcetype=syslog

    [monitor:///var/log/audit/audit.log]
    sourcetype=syslog
    index=

    [monitor:///var/log//maillog]
    index=
    sourcetype=syslog

I tried command

    sed -i -e 's/.*(?s)((\[monitor\:\/\/\/var\/log\/messages|secure\]).*?)(?:(?:\r*\n){2})' /index=secure *linux*/local/inputs.conf

to change the `index=` line to `index=secure` for the `messages` and `secure` log.


i) Work like a charm but the only issues I'm having right now is that, the 
 script cannot pass through the apps directory and update the index name and 
 most of the apps directory name is in this form.

     _EBPD_pr_linux_w1/local/inputs.conf,
     _EBPD_np_linux_w1/local/inputs.conf,
     _FBPV_pr_liux_e1/local/inputs.conf, 
    _FBPV_np_liux_e1/local/inputs.conf,
     _FBPV_np_windows_e1/local/inputs.conf,
     _FBPV_np_windows_e1/ocal/inputs.conf


ii) Secondly, the most important thing is that, if the app has `np` or `pr` that is how the index name will be updated. For example `index=secure_pr` or `scure_np` or `windows_pr` or `windows_np`.


iii) Another issue is that if there is an existing index name, it does not remove and update to the new index name it just adds to it. For example `index=power` is updated to `index=powersecure` instead of `index=secure`.


iv) I try these but it says "No such file or directory"

    perl -00lpe '$_.="secure_np" if m,/(messages|secure|cron|maillog|spooler|audit/audit\.log)\],' *linux*/local/inputs.conf 

    perl -00lpe '$_.="secure_pr" if m,/(messages|secure|cron|maillog|spooler|audit/audit\.log)],' *linux*/local/inputs.conf 

    perl -00lpe '$_ .= "windows_pr" if m,/(Application|Security|System|ForwardedEvents|Setup)\],' *window*/local/inputs.conf 

    perl -00lpe '$_ .= "windows_nr" if m,/(Application|Security|System|ForwardedEvents|Setup)],' *window*/local/inputs.conf
