how to change specific value for a entry in the file
Hello All,

can someone please suggest me a one line command to change a specific value that is associated to an entry in the file.
for example
Code:
#more schedulefile
quartz.job.manual.bonus.schedule=0 0 9 ? * *
#

it should be changed to
#more schedulefile
quartz.job.manual.bonus.schedule=0 0 1 ? * *
#

Thanks,

Code is correct, minor correction required:-

Code:
sed '/^quartz\.job\.manual\.bonus\.schedule=/s/[0-9]\{1,\}/1/3' testfile

And if you want to save the changes onto the file then use
Code:
 -i

option
