json - replace using bash - Dynamic value -


i have json file has following values

cat file     {     "key1": "value1"     "key2": "value2",     }

i change value1 , value2. values dynamic changes overtime. sed should work value , mylook should key. " sed command not helping.

 sed -i 's/*\"key2\":*/\"key2\": "someothervalue2"/' file

you should using proper json-parser instead of sed, e.g. jq.

infile

{   "key1" : "value1",   "key2" : "value2" }

you can replace values this:

jq '.key1 = "foo" | .key2 = "bar"' < infile

output:

{   "key1": "foo",   "key2": "bar" }

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
