windows - Delete all but one file loop with bat script -


i have loop in batch file delete 1 file in directory (windows 7). hangs because still sends commands screen, though i'd thought i'd suppressed it. here command i'm using:

for %i in (*) if not %i == update.bat del /s %i >nul 2>&1

tested batch script, log shows stops right @ command. tested command @ command line, outputs "del /s file.ext >nul 2>&1" command prompt each file in directory, causes batch file hang.

what need change here?

if directly in open cmd window , not batch,
can suppres output of current command leading @ sign.

@for %i in (*) @if /i not "%i"=="update.bat" @del "%i" >nul 2>&1

in batch toggle output of commands @echo off , double % signs of variable.

@echo off %%i in (*) if /i not "%%i"=="%~nx0" del "%%i" >nul 2>&1

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() .
