While googling for soft link and hard link i found this part
Code:
{
FILE *fp;
fp = fopen("some.hidden.file","w");
unlink("some.hidden.file"); /* deletes the filename part */
/* some.hidden.file no longer has a filename and is truely hidden */
fprintf(fp,"This data won't be found
"); /* access the data part */
I am running RHEL 5.4 Server (32-bit) and have my audit.rules file set up per a template that I am required to use. There is one particular rule that audit is auditing the unlink of files. With this set, my log files are filling up very fast, as there is a particular app that constantly touches/ deletes a couple of files, which the unlink is catching. Here is the audit rule:-a always,exit -F arch=b32 -S unlink -S unlinkat -S rename -S renameat -F auid>=500 -F auid!=4294967295 -k deleteI commented out the "-S unlink" and my logging returns to normal (as expected). For right now, I was wondering if there was a way to set this rule up to exclude these couple of files from what auditd is capturing?

I tried to link USB to com port. Mistakenly I managed to link to one USB several ports. How can I unlink them in order to have only one linked? This is how it looks like!

And second question, I have installation files for Redhat(73, 8, 9). Can I install them to Fedora 14? If yes, could you? please, help me with commands?
I installed Minecraft and I want to hide the .JAR extension on the file on my desktop. I tried just renaming it and deleting the ".jar" from the name, but when I tried opening it, it opened as an archive, rather than an executable, even though I had the "Allow executing file as program." box checked off. What can I do to hide the extension?
I'm using zenity 2.28.0 in a bash script (under kde4) to select multiple files in a directory. It works fine, but always defaults to showing hidden files. How can I get it to hide hidden files by default?
I know about toggling them on and off with Ctrl-H, but I would prefer not to have to use that. I have my options set so that dolphin and konqueror do not show hidden files by default. I even tried adding shopt -u dotglob to my script. zenity invocation (extracted from a more complex statement): zenity --title "Select Print Files to Delete" --file-selection --multiple
I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?
I currently have a UNIX script with a function that uses a username and password to connect to the database, retrieve some information and then exit. At the moment, am getting the username and password from a hidden plain text file and permission set to -r--------, i.e. read only to who own the file. The owner of the file is the same owner of the script. At the moment, am not too overly concern as the script works as it is but I want to know if anyone have a suggestion if there is any better way of achieving the same thing with some "form" of security, i.e., for example, masking the username/password.
Basically, I want to be able to mask or hide the username or password in some way. I've thought about encryting the password file, which is in plain text, using simple crypt command from which I retrieve the username and password but I need to decrypt it as well which is sort of similar to how it will be as it is now once it is decrypted. Is there anyway that I can get a username and password in some gibberish format and then translating them into something usable which can be passed on the next command that requires the username/password.
I need to be able to convert HTML email messages saved as text files (.eml or .msg) to PDF documents, one PDF per email, retaining formatting and images.
Are there any Linux tools that will allow me to do this from the command line (so it can be scripted)?
I want to scan a particular directory recursively and run a particular command with each file as input. For this I am using "find /dir/path". I dont want to write any long script containing loop on the output of "find". I want a single command which will allow me to run a command on each file of the "find" command output.
Recently I've started to learn cpp language on linux,and now I run a cpp file using following commands. g++ -o xxx xxx.cpp./xxxIs there a way to make it one line command such as compile-and-run xxx.cpp?
I want a quick and simple way to execute a command whenever a file changes. I want something very simple, something I will leave running on a terminal and close it whenever I'm finished working with that file. Currently, I'm using this: while read; do ./myfile.py ; done And then I need to go to that terminal and press Enter, whenever I save that file on my editor. What I want is something like this: while sleep_until_file_has_changed myfile.py ; do ./myfile.py ; done
Or any other solution as easy as that. BTW: I'm using Vim, and I know I can add an autocommand to run something on BufWrite, but this is not the kind of solution I want now. Update: I want something simple, discardable if possible. What's more, I want something to run in a terminal because I want to see the program output (I want to see error messages).
I am using the BackTrack 4 Live CD...and when I entered the "cat" command, it told me that no such command existed. I made absolutely sure that I a entering the command correctly. It just comes up with the word cat in quotes and says "no such file" or "no such command" something of that nature.

Does anybody know of tool for Linux that can watch a custom subtree of the filesystem for changes, and executes a custom command when a change occurs ? Such a tool would be very useful to quickly setup automatic building or uploading of source files.
This seems so simple when doing it from command line but I'm not able to accomplish it inside a script. I am trying to put output of following command into a text file:
CMD= mysql -uroot -psecret -e 'SHOW SLAVE STATUS G;' FIL=~/replication-`date +%F`.txt MAILTEXT=~/mailtext.txt touch $FIL $CMD > $FIL
Where FIL is a variable that contains path of the file to which to output command. I am running this command in a shell script from where I want to email contents of $FIL as attachment using mutt. But I am always getting 0 byte file. Also if I examine in directory the file is of 0 byte length.
