bash - trouble splitting a string by line and colon -


i know how split string such colon using ifs. however, script writing, running command returns me in format of

birthday      :      mon, date, year first day     :      mon, date, year

i want date of birthday. in order that, doing:

ifs=: read -r -a datearr <<< "$dates" echo "${datearr[1]}"

which ideally print date comes after "birthday :", unfortunately nothing printing. tips? should split string line well?

the expected output i'd is: mon, date, year (corresponding birthday field)

this tailor made job awk custom field separator:

awk -f '[[:blank:]]*:[[:blank:]]*' '{print $2}' file  mon, date, year mon, date, year

note ifs=:, string left padded spaces:

while ifs=: read -r -a datearr; echo "${datearr[1]}"; done < file        mon, date, year       mon, date, year

you can use remove spaces:

while ifs=: read -r -a datearr; echo "${datearr[1]//[[:blank:]]}"; done < file  mon,date,year mon,date,year

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

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() .
