An awk script for LDIF processing

ldap.awk

# Set the following values before any processing occurs:
#    RS (record separator) to an empty line
#    FS (field separator) to a newline
#    OFS (output field separator) to a comma
BEGIN { RS = "" ; FS = "\n" ; OFS=","}
{ for (i=1;i<=NF;i++) {
# Add a line for each field to be extracted, replacing the field name in
#  all three spots:
       if ($i ~ "^cn: ") { cn=gensub("^cn: ","","g",$i) }
       if ($i ~ "^title: ") { title=gensub("^title: ","","g",$i) }
       if ($i ~ "^uidNumber: ") { uidNum=gensub("^uidNumber: ","","g",$i) }
       if ($i ~ "^uid: ") { uid=gensub("^uid: ","","g",$i) }
      }
# Output content in the event that the fields are not blank
  if ( cn > "" && title > "" && uid > "" && uidNum > "" ) {
       printf("%s\n  title: %s\n  uid: %s\n  login: loginprefix-%s\n\n",  cn, title, uid, uid)
      }
# make sure to reset the values to blank
  cn="" ; title = ""; uid="" ; uidNum=""
