batch file - Calling bteq from Powershell -

i generate bat file contains multiple bteq calls execute .btq script against teradata box, below example cmd call:

bteq <bteq\"file_1.btq" >>bteq_output.txt 2>&1 

the syntax far understand is:

> specifies input file & >> specifies output file

i trying convert bat implementation powershell version stuck following issue:

ps c:\...\deploy.ps1:21 char:81 + ... -object { bteq < (join-path $deploydir $_) >> bteq_log.txt } +                    ~ '<' operator reserved future use. + categoryinfo          : parsererror: (:) [],parentcontainserrorrecordexception + fullyqualifiederrorid : redirectionnotsupported 

which result of call in powershell script:

(get-content -path $configfile) | select-object -skip 1 | foreach-object { bteq.exe < (join-path $deploydir $_) >> bteq_output.txt } 

it seems bteq command line syntax directly conflicts < operator in powershell.

edit if try escape < ` instead presented following error, though parameter not picked up:

bteq.exe :  *** warning: must log on before sending sql requests.  @ c:\...\deploy.ps1:20 char:76 + (get-content -path $configfile) | select-object -skip 1 | foreach-object { bteq. ... +                                                                            ~~~~~ + categoryinfo          : notspecified: ( *** warning: y... sql requests. :string) [], remoteexception + fullyqualifiederrorid : nativecommanderror 

anyone able shed light how 1 call bteq command in powershell when specifying file used?

in powershell try cat <your-bteq-file> | bteq call bteq file
