Stuck process when using sed command
Code:
$BIN/sql.py "select * from reporting.V_AMSNB_OPT_PB_LOAD" | sed -n "2,$ p"  | sed "s/   /,/g" > $DATADIR/OPT_PB_LOAD_AMSNB.csv
if [ $? -ne 0 ]

The processes that get created from the above code gets stuck...as in the processes get created but then never completes. (or at least we assume it never completes as we have been killing the process after a couple of hours) We use this exact same code except with a different database view and there are no issues with that particular code. It executes and completes just fine. I have tried runnign the same select statement as above at the database level and there is no issue retrieving the data.

It would seem as though there may be something related to the data that may be causing the process to get stuck? Does anyone know what could cause this process to get stuck? Smilie

LEARN ABOUT DEBIAN

fixnt

fixnt(1)							      Debian								  fixnt(1)

NAME

       fixnt - Filter for the Windows NT postscript printer driver.

SYNOPSIS

       fixnt < BADFILE.ps > GOODFILE.ps

DESCRIPTION

       The  Windows  NT  postscript  driver has a tendency to make broken postscript files, that are incompatible with psutils.  fixnt is a filter
       that fixes these problems, allowing the use of psnup(1).

       The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout.  It has no other form  for	invocation
       and takes no options on the command-line.

OPTIONS

       fixnt  takes no options.

BUGS

       fixnt does not check for NTPSOct94.  For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
	      sed 's/NTPSOct94/NTPSOct95/g'
       This is particularly important for Windows NT 3.5 users.

AUTHOR

       fixnt   was   written   by   Holger   Bauer   <Holger.Bauer@topmail.de>,  Michael  Rath	<rath@itsm.uni-stuttgart.de>,  and  Akim  Demaille
       <demaille@inf.enst.fr>.

REPORTING BUGS

       Report bugs to the Authors, but avoid sending large postscript files.

       Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
