find command with variables and *

Ratzie — Thu, 05 Nov 2009 15:49:51 GMT

I am trying to write a script for a backup.

I have parsed yesterdays date in a variable, taken for the oracle database.

I then want to do a find in a directory with that date (all my backup file name start with a date)

20091028_online_bu_copy_TS_USERS-ioksum8q
20091028_online_bu_copy_TS_SYSTEM-ipksumm4
20091028_online_bu_copy_TS_UNDOTBS1-iqksumn7
20091028_online_bu_copy_TS_SYSAUX-irksumo0
20091028_cf&spfile_NASMB_c-2956975978-20091028-03
20091029_online_bu_copy_TS_USERS-o7kt13mq
20091029_online_bu_copy_TS_SYSTEM-o8kt144o
----------------------
YESTERDAY=`sqlplus -silent " / as sysdba" << EOF
set pagesize 0 feedback off heading off verify off echo off
Select to_char(sysdate-1,'YYYYMMDD') from dual
Exit;
EOF`

# echo $YESTERDAY
# 20091028

So I am having problems trying to do a find of files in a directory with $YESTERDAY in the file name.

find . -type f -name '*$YESTERDAY_*'
- DOES NOT WORK.

Use " (double quotes) rather than ' (single quote).

find . -type f -name "*$YESTERDAY_*"

should work fine.

Nope it returns all.
