[SOLVED] update values defined in specific section of config file using bash

Issue

I am looking to update one config file using bash.

Config file is having multiple section like

[SECTION1]
action.email.useNSSubject = 1
dispatch.earliest_time = 1578927600
dispatch.latest_time = 1579016736
search = | inputlookup KPI_MASTER_LIST.csv | search TYPE="MTE_GENERIC" \
| table ALERT Order\
| map maxsearches=21 search="| savedsearch "$$ALERT$$" host_token=$host_token$ SERVICE_EARLIEST_TIME=$SERVICE_EARLIEST_TIME$ time_token.earliest=$time_token.earliest$ time_token.latest=$time_token.latest$ | appendcols [ | makeresults | eval Order="$$Order$$" | fillnull count ] | table ALERT count Order "\
| sort Order \


[SECTION2]
action.email.useNSSubject = 1
alert.track = 0
dispatch.earliest_time = 153437300
dispatch.latest_time = 1549013433
display.general.timeRangePicker.show = 0
search = | inputlookup KPI_MASTER_LIST.csv | search TYPE="MTE_GENERIC" \
| table ALERT Order\
| map maxsearches=21 search="| savedsearch "$$ALERT$$" host_token=$host_token$ SERVICE_EARLIEST_TIME=$SERVICE_EARLIEST_TIME$ time_token.earliest=$time_token.earliest$ time_token.latest=$time_token.latest$ | appendcols [ | makeresults | eval Order="$$Order$$" | fillnull count ] | table ALERT count Order "\
| sort Order \

I am looking to update value of "dispatch.earliest_time" and "dispatch.latest_time" in specific section only(not all occurrence of this file)

Solution

You could use an address range specifying your delimiter

sed '/\[SECTION_NAME\]/,/^\[/ s/dispatch.earliest_time/new_value_here/'

You can find thorough documentation about sed here
