Splitting a file
I have a source file where a record starts with # entry-id: followed by a number.
i want to move the record in file 1 iff the second row is
Code:
"dn: uid=.*,ou=perm,dc=mssb,dc=com"

and the record to file 2 if contents of second row anything else
Code:
# entry-id: 1
dn: uid=abcd,ou=perm,dc=mssb,dc=com
Entry3
Entry4
Entry5
Entry6
Entry7
Entry8

# entry-id: 2
dn: uid=efgh,ou=term,dc=mssb,dc=com
Entry3
Entry4
Entry5

# entry-id: 3
dn: uid=xidydh,ou=perm,dc=mssb,dc=com
Entry3
Entry4

so Entry id 1 and Entry id 3 should be in file1 and entry-id2 to file 2

Howsoever, try
Code:
awk '{print $0 ORS > "file" 2- ($2 ~ /dn: uid=.*,ou=perm,dc=mssb,dc=com/)}' RS="" FS="\n" file

Thanks RudiC.

I wanted to sort the file as well based on
Code:
# entry id 1

value. Using sort command but unable to do so.

How about
Code:
awk '{gsub (FS, "\t")}1' RS="" FS="\n" file1 | sort -k3,3n |  awk '{gsub ("\t", FS); print $0 ORS > "FILE" 2- ($2 ~ /dn: uid=.*,ou=perm,dc=mssb,dc=com/)}'  FS="\n"

Hi RudiC,
in code
Code:
awk '{print $0 ORS > "file" 2- ($2 ~ /dn: uid=.*,ou=perm,dc=mssb,dc=com/)}' RS="" FS="\n" file

Kindly explain what is the purpose of highlighted part-, also this code is not working in my linux.

The ~ match operation will result a boolean result, 0 or 1, which is subtracted from 2 to yield the desired file names. Please note that the use of boolean results in arithmetic operations is not commonly accepted.

Try the script again with the file name concatenation in parentheses.

And, "is not working" is quite poor an error description to analyse and track down the error.
