View 3 Replies View RelatedI am trying to write input to a shell and get the shell to parse the input that I am writing to it as if a user was typing in commands.
Thus far I have tried echoing some text into the shell's FD for STDIN in /proc/<pid>/fd Whilst this displays the text that I echo, the shell that I am writing to never tries to execute the command that I pass to STDIN. What is the difference between a shell taking STDIN from the user and data written to STDIN by another process e.g. echo ? It appears I am missing something fundamental.
I want to perform an action with a shell script and then log the event in a file in /var/log. However, I keep getting permission denied error messages.
View 5 Replies View RelatedI am about to write my first shell script for backing up my server.
These are the steps I have identified so far.
Copy files to be backed up to /srv/backup/ run mysqldump and copy the file to srv/backup/databases run duplicity to backup /srv/backup/* to another folder on my machine
I am writing a bash shell scrip that will be run everyday, and will carry out the three tasks mentioned above.
Note: point 3 (backing up to a local folder) is only a temporary measure - to allow me to understand what I'm doing, since all the tools I am using, are new to me. Once I can backup and restore correctly, I will use duplicity to compress and encrypt the files and upload them offsite.
If my understanding of duplicity is correct (according to the documentation here), the first time I run the script, a FULL backup will be done. Every subsequent backup will then be incremental. I will then force a FULL back on say a weekend.
First things first though - I have a few questions:
I would like to use backup rotation for the 'scheme' described above - I would like some recommendations on what kind/type of rotation to use. Once I have implemented the backup rotation, how can I restore from a particular day back in time (assuming the backup exists of course). ?
I am running Ubuntu 10.0.4
I am new to Linux, I have just understood the very basics of the command line and the file system, but I am still having practical problems: Here is the biggest so far: I just installed IRAF (An Astronomical Image editing sofware) and even though it prompted me with "Successfully installed", when I want to run the application it gives me this error:
Code:
/iraf/iraf/bin.linux64/ecl.e: error while loading shared libraries: libtermcap.so.2: cannot open shared object file: No such file or directory
Looking around in the internet I saw some users had proposed a symbolic link to libncurses.so.5.7 since it seems ncurses has replaced termcap. But even though I made this link:
Code:
$ls -l libtermcap.so.2
lrwxrwxrwx. 1 root root 17 Dec 6 11:04 libtermcap.so.2 -> libncurses.so.5.7
I still get the same error.
I made the same symbolic link, named libtermcap.so.2 in both my /usr/lib/ and /lib/ directories to the /lib/libncurses.so.5.7 since some users had mentioned /usr/lib/ and some /lib/.
I am running Fedora 14 (64bit) on my system and this version of IRAF 2.15 is made for 64bit systems.
I want to write a single shell script that allows me to, once executed from a panel launcher, change the image preview setting between "local files only" and never. Right now i have two tiny scripts, one for local files only and another one for never, that is:
[Code]...
and the other says string "local_only". But that means i need to have two launchers, because i don't know how to write the condition <<when set to never, change it to local only. And is it possible to make a script that also changes the launcher's icon when the preview config is set to one or the other value? That way i'd know what it is set to just by looking at it. It would act as a diagnostic and therapeutic tool XD
I am writing a script that is designed to verify an application is running. The if...else statement in question is the following:
Code:
# Check if <application> is running.
ps -ef |grep <application> > /dev/null
RC=$?
echo $RC
[Code]....
I have started testing by disabling the application in question, and then running the script. The problem that I am seeing is that even though the application is not running, I am getting an output code of 0 due to the successful running of the ps command. What syntax change(s) do I need to make in order to accurately determine when the application is not running?
I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code:
if [ $# -eq 0 ] ; then
d=`pwd`
for i in * ; do
if test -d $d/$i ; then
echo "$i:"
code....
Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)
...
[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.
I am going to write a TCP server program using c. Can anyone give me some advices on whats and what not to do specially when using select?
There would be a lot of data to be transferred both on the server and back to the client. I already have a simple server here but the server uses a lot of resources. Maybe 3 to 4 connections and the server's load would rise to unacceptable levels.
Which do you think is better to use fork or select?
I want to write some PHP for a website that'll have the data that the script will generate written inside a table with thin black line around it, much like LQ itself. My problem is: how do I draw the box that the text will be inside of, since the amount of text will vary - if I have a GIF with a picture of a box, that'll be of a fixed length, and my script can then only generate that much text, for it to look nice. Or do I need to fiddle with the GD library to get done what I want?
View 4 Replies View RelatedSo basically, there is a really cool writing system I have been working on. It could be viewed (for simplification purposes) like an encryption method for the Latin script.
Facts about the writing system:
It has a little over 300 symbols.
It is syllable-driven.
It is highly compositional (eg. "c", "ca", "cae", "ca " and "ci." all map to different symbols - and NOT by overlaying elements)
Symbols have medium graphical complexity (comparable to Korean Hangul, or Japanese Hiragana)
Has a rather complex set of diacritics (~10, some of which can go on any symbol)
Has no ligatures
How transliteration occurs:
Sequences of Latin symbols map to certain symbols. Example below:[G][rou][p ][hu][g.]Characters sequences between "[" and "]" map to a single symbol (so it would take only 5 symbols to write "Group hug.").
How I want it to work:
I would like to have a daemon that: Intercepts all text displayed on the screen.
Converts it to my writing system (changes letter sequences with individual Unicode codes)
Leaves unsupported symbols unchanged.
Displays all the text on the screen using my font and characters intertwined with the fonts and characters left unchanged.
For example, if you take the following line of C++ code:for (i = 1; i <= n; i++)
I would like it displayed like this:[fo][r ]([i ]= [1]; [i ]<= [n]; [i]++)
Bold-symbols should be in my Unicode font with special symbols defined for this writing system, and the rest should be in its original font and encoding. Also, I would like this encoding to hold for display-purposes only. The data in the memory should remain unaffected. This also means real-time adjustments: if I open a text editor (say, from the OpenOffice Suite) and I start typing, I would like to see what I type encoded with my writing system, even though the document actually contains Latin letters. This also means that the symbol immediately before the cursor may change as you type.
I have written a daemon server. I would like to add the ability for the daemon to update itself. That is, it should be able to download the latest version of the code (when it receives a signal from a client) and then restart itself. I am stuck on getting the daemon to restart itself. The problem is killing the old daemon without killing the process that is starting the new daemon. In my latest attempt, the daemon that is updating itself runs a program in a subshell (using system) that starts a restarter daemon that runs the original daemon (again using system) with the restart command option. With the restart option, the new version of the daemon sends a terminate signal to the old version. Obviously, when I run the original daemon manually with the restart option, it restarts reliably. I figured that issuing the same restart command from a daemon would adequately isolate the process doing the restarting from the program being restarted. Using ps, I can see that the daemon does actually restart. However, the client locks. In fact, a few times, the OS locked and I had to reset.
