Read in data from 100,000+ files via command line

I had originally asked the following question:
http://www.experts-exchange.com/Programming/Languages/Scripting/Shell/Q_28329553.html

This at first seemed like it work exactly the way I needed, however I just discovered that lines with spaces were not correctly read in.

Below is the last iteration of the code:
#!/bin/sh

echo `date`
find . -name "*.arf" | while read f; do
  newpath="$(basename $(dirname "$f"))"
#/$(basename $f)"
  cat "$f" | gawk -v p="$newpath" '{ 
    attname=substr($1,1,length($1)-1); nlist=nlist"`, `"attname;
    attvalue= substr($2,2,length($2)-2); vlist=vlist", '\''"attvalue"'\''";
  }
  END { 
    printf "insert into `mydatabase`.`archives` (`NEWPATH%s`) values ('\''%s'\''%s);\n", nlist, p, vlist;
  }' >> myinsertfile.sql
#| tee -a myinsertfile.sql
  cnt=$((cnt+1))
  [ $(($cnt%100)) -eq 0 ] && echo "File #$cnt: $f"
done

echo "Total Files: $cnt"

echo `date`

Open in new window


For the following .arf file:
FILEID: "TIF490336"
PATH: "/optical/incoming/TIF490336"
TYPE: "TIF"
SECLEV: "10"
STATID: ""
USRID: "admin"
REQDATE: "08/02/2012"
REQTIME: "09:02:32"
GENDATE: "08/03/2012"
GENTIME: "09:02:32"
PROGID: ""
GROUPID: "Check Stubs"
DESC: "August"

Open in new window

It produced the following SQL statement:
insert into `mydatabase`.`archives` (NEWPATH,FILEID,PATH,TYPE,SECLEV,STATID,USRID,REQDATE,REQTIME,GENDATE,GENTIME,PROGID,GROUPID,`DESC`) values ('TIF18','TIF490336','/optical/incoming/TIF490336','TIF','10','','admin','08/02/2012','09:02:32','08/03/2012','09:02:32','','Chec','August');

Open in new window


Which resulted in the GROUPID column containing incorrect values.  How can the code above be adjusted to process spaces as well?

The problem is that gawk is splitting fields on spaces (its default).  If you change it to split on : or " characters, you can change 4 lines of the code to:
  cat "$f" | gawk -F'[:"]' -v p="$newpath" '{ 
      nlist=nlist "`, `" $1;
      vlist=vlist ", '\''" $3 "'\''";
      }

Open in new window

The rest of the script stays the same.  This assumes that the format of the input file is consistent (in particular, that there is one colon immediately after the first name, and the value field is always enclosed by double quotes).

Perfect, that's exactly what I needed!
