Shell Programming and Scripting

Hi,

I have shell script which will read single edi document and break data between ST & SE to separate files.Below example should create 3 separate files. I have written script with the below command and it is working fine for smaller files.

Code:

awk -F\| -vt=`date +%m%d%y%H%M%S%s` \
  '$1=="ST",$1=="SE"{if($1=="ST"){close(f);f="edi850."t"" ++i} ; $1=$1; print>f}' OFS=\| inputfile

If i run it using large file around 10 MB, then it is not working. It is writing partial file. Please help me with the correct code.

example

Code:

ST|850
BEG|PO|1234
LIN|1|23
SE|4
ST|850
BEG|PO|234
LIN|1|43
LIN|1|41
SE|5
ST|850
BEG|PO|345
LIN|1|53
SE|4

Some versions of awk do not close files correctly.

If

Code:

ulimit -n

is less than the total number of possible output files then this may be the problem.

What OS and version of awk?

Code:

# some awks
what `which awk`
# GNU awk
awk --version

will give you version information.

OS Version - AIX 3

aix:/home $ what `which awk`
/usr/bin/awk:
61 1.15 src/bos/usr/ccs/lib/libc/__threads_init.c, libcthrd, bos53H, h2006_10B1 3/5/06 16:44:58
