Issue
I have a file which has this data -
view:
schema1.view1:/some-path/view1.sql
schema2.view2:/some-path/view2.sql
tables:
schema1.table1:/some-path/table1.sql
schema2.table2:/some-path/table2.sql
end:
I have to read the file and store the contents in different variables.
viewData=$(sed '/view/,/tables/!d;/tables/q' $file|sed '$d')
tableData=$(sed '/tables/,/end/!d;/end/q' $file|sed '$d')
echo $viewData
view:
schema1.view1:/some-path/view1.sql
schema2.view2:/some-path/view2.sql
echo $tableData
tables:
schema1.table1:/some-path/table1.sql
schema2.table2:/some-path/table2.sql
dataArray=("$viewData" "$tableData")
I need to use a for loop over dataArray so that I get all the components in 4 different variables.
Lets say for $viewData, the loop should be able to print like this -
objType=view
schema=schema1
view=view1
fileLoc=some-path/view1.sql
objType=view
schema=schema2
view=view2
fileLoc=some-path/view2.sql
I have tried sed and cut commands but that is not working properly. And I need to do this using shell script only. Any help will be appreciated. Thanks!
Solution
remark: If you add a space character between the :
and /
in the input then you would be able to use YAML-aware tools for parsing it robustly.
Given your sample input you, can use this awk
for generating the expected blocks:
awk '
match($0,/[^[:space:]]+:/) {
key = substr($0,RSTART,RLENGTH-1)
val = substr($0,RSTART+RLENGTH)
if (i = index(key,".")) {
print "objType=" type
print "schema=" substr(key,1,i-1)
print "view=" substr(key,i+1)
print "fileLoc=" val
printf "%c", 10
} else
type = key
}
' data.txt
objType=view
schema=schema1
view=view1
fileLoc=/some-path/view1.sql
objType=view
schema=schema2
view=view2
fileLoc=/some-path/view2.sql
objType=tables
schema=schema1
view=table1
fileLoc=/some-path/table1.sql
objType=tables
schema=schema2
view=table2
fileLoc=/some-path/table2.sql
