Hope you can help out a scripting newbie here. A forum search hasn't given me what I'm looking for. I need to fish out all the alias entries in our LDAP database and match them to the proper user names. I've decided to output a comma delimited file.
If a user has one alias, no problem, that much I've got figured out. It's the users with multiple aliases that have got me stumped. I tried this ham fisted approach(I'm guessing no one has more than 5 aliases):
BEGIN {
UserID = ""
DisplayName = ""
Alias = ""
printf(" UserID,DisplayName,Alias,Alias,Alias,Alias,Alias\n");
}
/^uid: / {UserID=$2}
/^displayName: / {DisplayName=$2" " $3}
/^alias: / {Alias=$2}
/^dn: / {
if(UserID != "") printf("%s,%s,%s,%s,%s,%s,%s\n",UserID,DisplayName,Alias,Alias,Alias,Alias,Alias)
UserID = ""
DisplayName = ""
Alias = ""
Alias = ""
Alias = ""
Alias = ""
Alias = ""
}
END {
printf("%s,%s,%s,%s,%s,%s,%s\n",UserID,DisplayName,Alias,Alias,Alias,Alias,Alias);
}
This prints 5 instances of the first alias, not what I'm looking for. I'm thinking a loop of some kind is what I'm looking for, but I'm not sure how/where to put it. Any pointers would be appreciated. thanks.

You have to put the aliases into an array. When it's time to print, you have to print each array element; I got your source and modified it as an example:
Code:
function print_user()
{
if(UserID != "")
{
printf("%s", UserID)
for (i = 1; i <= ind; i++)
printf(",%s", Alias[i])
printf("\n")
}
}
BEGIN {
UserID = ""
DisplayName = ""
Alias = ""
printf(" UserID,DisplayName,Alias,Alias,Alias,Alias,Alias\n");
}
/^uid: / {UserID=$2}
/^displayName: / {DisplayName=$2" " $3}
/^alias: / {Alias[++ind]=$2}
/^dn: / {
print_user()
UserID = ""
DisplayName = ""
ind = 0
}
END {
print_user()
}

Alias = ""<======I had to remove this.
printf(" UserID,DisplayName,Alias,Alias,Alias,Alias,Alias\n");
}
/^uid: / {UserID=$2}
/^displayName: / {DisplayName=$2" " $3}
/^alias: / {Alias[++ind]=$2}
/^dn: / {
print_user()
UserID = ""
DisplayName = ""
ind = 0
}
END {
print_user()
}
Thanks a lot, that worked fine!
One quick note, I had to remove the "Alias" variable. The script was throwing scalar context errors(see note above).
