Remove spaces and special characters from Linux file names

Oracle Database Tips by Donald BurlesonFebruary 24,  2015

One of the problems with Linux in Oracle is that you are allowed to create Oracle data files (.dbf files) that contain special characters like spaces and punctuation marks.

When you create a Oracle data file with special characters all sorts of strange things may happen, and the best solution is to re-name the data file without the special characters:

1 - Take the tablespace offline

2 - Fix the data file name (see script below)

3 - re-name the data file

4 - put the tablespace online

Here is a script from Penguin Pete that will detect and repair all Oracle Linux data files that contain a "space", replacing it with an underscore:


ls > /tmp/list
# we have to make the list file in a separate
# directory so that it doesn't get included
# in the list of the current directory!
mv /tmp/list ./list
cat list | tr ' ' '_' > listnew
# this turns spaces into underscores
FILE_COUNT=$(wc -l list | awk '{print $1}')
while [ "$LOOP" -le "$FILE_COUNT" ]
# the command to feed awk
# output will be 'FNR==1', 'FNR==2', ..
  OLDFILE=$(awk $AWKFEED list)
  NEWFILE=$(awk $AWKFEED listnew)
# keep the quotes to make the shell read file
# names with spaces as one file

rm list
rm listnew

exit 0
