we have this line from postgresql.conf file
#BARMAN# archive_command = 'rsync -a %p [email protected]:/var/lib/barman/main-db-server/incoming/%f'
I remove the word - #BARMAN# by the following sec syntax
sed '/archive_command/ s/#BARMAN#//g'
but the word archive_command not in the beginning of the line
as the following:
archive_command = 'rsync -a %p [email protected]:/var/lib/barman/main-db-server/incoming/%f'
while expected output should be
archive_command = 'rsync -a %p [email protected]:/var/lib/barman/main-db-server/incoming/%f'
how to fix that?
Notice that you are only replacing #BARMAN#, and not the space(s) afterwards.
To do that, use
sed '/archive_command/s/#BARMAN# *//'
or, to allow for tabs as well as spaces:
sed '/archive_command/s/#BARMAN#[[:space:]]*//'
This will remove the string and any number of spaces or tabs directly afterwards.
