Suppose I have a binary program with only execute permission enabled for the current user. How (in general) would I be able to obtain a core dump of the file? I think I have read it somewhere but I want to know if there are more ways of doing it.

-rw-r--r-- asper.sh I guess the permission should look like '-rwxr-xr--' How can I change the permission to be like that?
Here are some example files that are shared through samba:
-rwxrwx--- user1 group1 file1.txt
-rwxrwx--- user1 group1 file2.txt
When user2 (who is also a member of group1) edits file2.txt the permissions change:
-rwxrwx--- user1 group1 file1.txt
-rwxrw---- user2 group1 file2.txt
user1 then has issues opening the file. This also goes for new files that are created (they are missing the group execute permission).
I have set the option "create mask = 0770" in my smb.conf. Without this set, permissions default to something like -rwxr--r--

Binary files need only execute permission to execute. No read permission is required. But all executable files must be read by the kernel into main memory before executing. Also script files need both read and execute permissions for executing the file.

View 9 Replies View RelatedI just found that I could perform write operation using a normal user account to a file system I mounted with the commands as followed:
sudo mount -t ntfs /dev/sda1 /mnt/disk/
This is the corresponding entry in the output of "mount" command:
/dev/sda1 on /mnt/disk type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
As far as I remember, when using a normal user account, I had to use "sudo" to perform any write operations (mkdir, rm, etc) to a device mounted using "sudo". But now it seems to be changed.
Do I remember wrong, or did Karmic have any updates change this setting? (I never manually changed user settings, except that I added a root user, but I never used it.)

am fiddling around using an AES encrypted password which is stored in passwd.txt:cat ../passwd/passwd.txt
{AES}yTMWTrdbuPtCxikvv5udVDTQ70anBVVKvP+GPQEH1RY=Yet I like to interpret this password on the command line using svn checkout, so I do not have to type in my password ( which is visible on the command line):Exporting the variable SVNPASS reading it from the passwd.txt ( export SVNPASS=`cat <../passwd/passwd.txt`) won't work obviously as it interprets it as "text", so my question is, if there is a proper way to interpret this stored AES password so I can read it from the file?The alternative is to type in the password on the command line, but this needs to be invisible eitehr showing #, * or "hidden".
the last option is described: http://www.tech-recipes.com/rx/278/h...-shell-script/

I was running '# ls -l' in '/' directory and I noticed all directories in '/' have the following permeation 'drwxr-xr-x' [except root's home which is 'drwx------' (after I change it from 'drwxr-xr-x' )]
I don't want all the user (except root) to be able to read and execute (in) any directory, I just want every user to be abel to read/write/execute only in his/her home directory.
my question is, is it ok to change file and directory permeation of the following directories in '/' from 'drwxr-xr-x' to 'drwxr-x---' or 'drwx------' recursively?

I'm using ubuntu 11.04, I'm having some problem of ownership while sharing folder/files. to share i change the folder share option:1. Share this folder, then followed by 2.allow others to create and delete files in this folder3. guest access.Now if someone in my local network edit any file and save it, it gets locked. if some one copy their file in this folder the permission is marked as "no group" "no owner". and they get unaccessible to me. i tried doing chown <user> <folder> but it says Operation not permitted. Now how i can possibly share my folder on local network so that they can be edited by others without getting locked down , if they copy files i can able to modify them.

This is weird, today I updated my system and while trying to visudo from single user mode got

which kept me from doing anything until I switched to file permissions of 400 on shadow, then back.

I am splitting a file based on the values read from an input file. The below one is the script.
1)How do I add the header which is present in the original file to the new split files created?(For eg. pharmacyf conatins header as table column names. The new files created (ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat) are without the header).
2) Also the script is creating 0 byte files for the pharmacyids which are not available in the intial file? Can this be avoided?
for pharmacyf in *
do
tablename=`echo $pharmacyf |cut -f4 -d'.' `
while read pharmacyid
do
grep -w $pharmacyid $pharmacyf >> $OUT/ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat
done< inputfile
done
