Bash - saving string to separate variable after custom delimiter -


i'm new bash please forgive me, i'm building bash script can accept user input command can have lot of switches. need write function pulls specific data user provided command.

i can't seem find way pull each word after "-mode" , push array or list of sort.

here example of user input command might like:

/home/custom/function/that/accepts/a/billion/switches  random_info random_info2 -worker vendor_schmo  -switch_one  -anotherone  -more_switches  -optiontwo        -mode foo -mode bar -mode baz -mode bag -mode dat -mode rar

i've tried fiddling awk -f "-mode" '{ print $1 }' , didn't work. advice appreciated!!

here snippet script pulls info:

manualrunmain(){   local command   manualrunheaderprint   echo   echo   echo   echo   linebreakprint   read -p "enter command here: " command   sleep .25   manualrun "$command" }  manualrun(){   manualrunheaderprint   jobrunsubheaderprint   pullmodenames "$1" }  pullmodenames(){  }

you can use rs variable in awk tell split data separate records when -mode:

s='/home/custom/function/that/accepts/a/billion/switches  random_info random_info2 -worker vendor_schmo  -switch_one  -anotherone  -more_switches  -optiontwo        -mode foo -mode bar -mode baz -mode bag -mode dat -mode rar'  printf '%s' "$s" | awk -v rs="-mode[[:space:]]*" 'nr>1' foo bar baz bag dat rar

to populate array:

mapfile -t arr < <(printf '%s' "$s" | awk -v rs="-mode[[:space:]]*" 'nr>1')  # examine array content declare -p arr declare -a arr=([0]="foo" [1]="bar" [2]="baz" [3]="bag" [4]="dat" [5]="rar")

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...

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() .
