regex - Sed not reading multiline input? -

i have text below:

path => ["/home/desktop/**/auditd.log",         "/home/desktop/**/rsyslog*.log",         "/home/desktop/**/snmpd.log",         "/home/desktop/**/kernel.log",         "/home//desktop/**/ntpd.log",         "/home/desktop/**/mysql*.log",         "/home/desktop/**/sshd.log",         "/hme/desktop/**/su.log",         "/home/desktop/**/run-parts(.log"     ]  

i want extract values inside [ ], doing:

sed -n 's/.*\[\(.*\)\]/\1/p' 

sed not returning anything.

if sed -n 's/.*\[\(.*\)log/\1/p it's returning string between [ , log.

"/home/desktop/**/auditd.", 

so it's able search within line.

how make work??

edit:

i created file content:

path => [asd,masd,dasd sdalsd,ad asdlmas;ldasd ] 

when grep -o '\[.*\]' not work grep -o '\[.*' returns 1st line [asd,masd,dasd. it's working single line not multiple lines.

try doing :

$ grep -o '".*",?' file 

output:

"/home/desktop/**/auditd.log", "/home/desktop/**/rsyslog*.log", "/home/desktop/**/snmpd.log", "/home/desktop/**/kernel.log", "/home//desktop/**/ntpd.log", "/home/desktop/**/mysql*.log", "/home/desktop/**/sshd.log", "/hme/desktop/**/su.log", "/home/desktop/**/run-parts(.log" 

• -o grep print matching part
• " literal double quote
• .* anything
• " si closing double quote
• , literal double quote
• ? mean o or 1 occurrence
