Cut only time from string

Hi Guys,

I have following different lines separated by multiple spaces. And i need to cut only the time part (16:53) from the string. How can we achieve it?

Code:
remedy   29210     1  1 07:55 ?        00:06:20 /opt/bmc/java/jre1.6.0_17/bin/java -Xms1024m -Xmx2048m -XX:MaxPermSize=1024m -Djava.awt.headless=true

Code:
remedy   25883     1  2 07:53 ?        00:10:46 /opt/bmc/java/jre1.6.0_17/bin/java -Xms1024m -Xmx2048m -XX:MaxPermSize=1024m -Djava.awt.headless=true

There are 3 spaces between 'remedy' and '29210' aqnd likewise goes on.

Please let me know how can we cut only 07:55 and 07:53 from these lines.

Thanks,
Khushbu.

Try:
Code:
awk '{print $5}' file

if it is a single line string, (in bash/ksh93/zsh) you could also use:
Code:
read x x x x time x <<< "$var"

or in general you could use:
Code:
read x x x x time x << EOF
$var
EOF

Which would put the time in the variable time

Try extending Scrutinizer's awk proposal:
Code:
awk '$5 ~ /07:53|07:55/{print $5}' file

Hi RudiC,

The time will be runtime value. I cannot pass this static value through this as illustrated in your example.
I need the 5th field (07:55) to be cut which is separated by multiple spaces.
Please help.

Hello Khushbu,

If time comes always in 5th field then you can try following.
Code:
awk '{print $5}' Input_file

If time's field is not set then you could try following.
Code:
awk --re-interval '{match($0,/[0-9]{2}:[0-9]{2}/);print substr($0,RSTART,RLENGTH)}' Input_file

Hope this helps.

Thanks,
R. Singh

Hi Ravinder,

Thanks a ton for your previous answer to my post regarding grep time form string. Its working amazingly!

Now, i have stored this time in lastrestart.txt file as follows:

Code:
07:25


Also, i have stored current system time in now.txt file as follows:


Code:
09:38

Now, i want to calculate the difference between these two times in hours only, in a variable. We follow 24-hr format time and hence would need to consider that format too.

Can you please help me in this?

Awaiting your response Smilie
