Windows file names with space at end

admin — Thu, 18 Jun 2009 23:45:33 +0000

Have a file or directory that you can’t delete because there is a space at the end of the file name?

If you try and delete from windows you will get the error message
“Error Deleting File or Folder”
“Cannot delete file: Cannot read from the source file or disk.”

To manipulate these files you need to address their absolute path with the prefix of “\\?\”

To do this you need to access these files from the command line.
Start -> Run -> CMD
del “\\?\c:\dir\filename ”

Make sure to include the quotes in above command.

#!/bin/bash
#This example is for a linux server using the following directory stucture to store email
#/home/unix-username/mail/domain/email-username/Maildir/.INBOX.spam/(cur | new)

#the following command will find all spam messages system wide over 14 days old and remove them
/usr/bin/find /home/*/mail/*/*/Maildir/.INBOX.spam/*/ -type f -ctime +14 | xargs /bin/rm -f

#-ctime n*24 hours
#-cmin n minutes
#-ctime +7 = > 1 week

Script – Avoid argument too long error

admin — Thu, 18 Jun 2009 23:02:25 +0000

When removing 10,000’s of files with rm -f * you get an argument too long error.

#### Remove too man files.
#### First find -name ‘*’ > filelist

#!/bin/bash
for i in $( cat filelist );
do
echo $i
rm -f $i
done
#####
##### Easier way to remove too many files right from command line
#####

ls|xargs rm -f

Script – find and replace

#########
#
# change the same value in all files showen under ls in a directory
# good for mass IP changes
#
##########
#!/bin/bash
for i in $( ls );
do
sed -i ’s/find/replace/g’ $i
done

Script – bash while loop

admin — Thu, 18 Jun 2009 22:15:55 +0000

#!/bin/bash
while read line;
do echo “” >> cities.out;
done < cities.in

# above processes a text file where a line item might contain spaces
# a for loop that cat’s the file will process each space as a separate item
#!/bin/bash
x=1
while [ $x -le 100 ]
do
echo “Hello World – $x times”
x=$(( $x + 1 ))
done
