I want to edit existing service name from /etc/services, tried below

augtool> print /files/etc/services/service-name[.="test"]
/files/etc/services/service-name[1] = test
/files/etc/services/service-name[1]/port = 01
/files/etc/services/service-name[1]/protocol = tcp
/files/etc/services/service-name[1]/#comment = #test
/files/etc/services/service-name[2] = test
/files/etc/services/service-name[2]/port = 01
/files/etc/services/service-name[2]/protocol = udp
/files/etc/services/service-name[2]/#comment = #test

I want to change service name

method 1:
augtool> set /files/etc/services/service-name[.="test"][protocol = "tcp]  "test1"
autool> save
method 2:
augtool> mv /files/etc/services/service-name[.="test"][protocol = "tcp]  "test1"
autool> save

I got saved file 1, but when checked /etc/services I don't find the changes what I made( both mv and set changes). In the time stamp shows the file edit time.

I am testing for commenting out the file

edit retag flag offensive close merge delete

Method #1 worked fine for me, but your command does have a syntax error. Maybe that's the problem? Please change:

set /files/etc/services/service-name[.="test"][protocol = "tcp]  "test1"


set /files/etc/services/service-name[.="test"][protocol = "tcp"]  "test1"

Note the missing double-quote after tcp


There is no good way to deal with comments in Augeas, and you have to look through this document to determine the best solution for you: Since Puppet wraps the usage of Augeas with the augeas resource, once you decide on a technique, you should be able to implement it in your Puppet code.

Greg, missing double-quote in tcp is typo. but when use "#test1" with set, I am getting error. Also I tried "mv /files/etc/services/service-name[.="test"][protocol = "tcp"] "#test1" " got file 1 saved message. But the entire line missed from /etc/services. Not sure why the commented line missing.
