Exact string match in multi line string

Arun Shankar · 06-19-2014, 03:32 AM

I have a string as below, I needed to exactly match if string "abc.properties abc Scanner directory: /xyz/xzy/" is present. I am using the below awk command. But, it considers as successful if even a part of string, say, abc.properties is present. But, my criteria is to check for the exact string i.e. "abc.properties abc Scanner directory: /xyz/xzy/". Can somebody please help?

Code:

echo $s | awk 'BEGIN { FS="\n"; RS="";} /abc.properties abc Scanner directory: \/xyz/xzy\// {print $1}'

String is as below:

Code:

spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no -o ServerAliveInterval=600 -o ServerAliveCountMax=3 -o ConnectTimeout=30 xyz@123.abc.com Password: Creating directory '/home/xyz'. Authorized uses only. All activity may be monitored and reported. Successful login using -u option. If you want to allow X traffic please use -x option. Usage: /111/11/111/111 [policy] -x [target user] su from xyz to abc [abc@xyz ~]$ /111/111/111/111/111/111.sh /111/11/instance/111/111/111/111/ Verifying JVM setting for domain: /111/11/11/11/1111/111/111// abc.properties abc Scanner directory: /xyz/xzy/ [abc@xyz ~]$ exit 0 logout

Arun, if you want to match the eaxct string , you can use the /^<to match>$/ of awk:

for eaxmple:

Code:

s='abc.properties abc Scanner directory: /xyz/xzky/'

Code:

echo $s |awk '/^abc.properties abc Scanner directory: \/xyz\/xzky\/$/'

This will return if string is there.

but

Code:

s='spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no -o ServerAliveInterval=600 -o ServerAliveCountMax=3 -o ConnectTimeout=30 xyz@123.abc.com Password: Creating directory '/home/xyz'. Authorized uses only. All activity may be monitored and reported. Successful login using -u option. If you want to allow X traffic please use -x option. Usage: /111/11/111/111 [policy] -x [target user] su from xyz to abc [abc@xyz ~]$ /111/111/111/111/111/111.sh /111/11/instance/111/111/111/111/ Verifying JVM setting for domain: /111/11/11/11/1111/111/111// abc.properties abc Scanner directory: /xyz/xzy/ [abc@xyz ~]$ exit 0 logout'

Code:

echo $s |awk '/^abc.properties abc Scanner directory: \/xyz\/xzky\/$/'

will not return anything.

Seems to work just fine for me

Not sure how the output of 'spawn' helps at all but it does return:

Code:

$ echo "spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no -o ServerAliveInterval=600 -o ServerAliveCountMax=3 -o ConnectTimeout=30 xyz@123.abc.com Password: Creating directory '/home/xyz'. Authorized uses only. All activity may be monitored and reported. Successful login using -u option. If you want to allow X traffic please use -x option. Usage: /111/11/111/111 [policy] -x [target user] su from xyz to abc [abc@xyz ~]$ /111/111/111/111/111/111.sh /111/11/instance/111/111/111/111/ Verifying JVM setting for domain: /111/11/11/11/1111/111/111// abc.properties abc Scanner directory: /xyz/xzy/ [abc@xyz ~]$ exit 0 logout" | awk '$0 ~ "abc.properties abc Scanner directory: /xyz/xzy/"{print $1}'
spawn
