Programming :: Write A Bash Script That Will Make Some Web Stats Reports
Jun 23, 2010
I'm planing to write a bash script that will make some web stats reports and I'm stuck on beginning because I don't know how can I read a directory content, put everything in a variable, compare the variable value with current date and go further.More specific ...
I have /var/apache/log/. Here I have access logs on date ( like access.log.24.06.2010.gz and so on ).
How can I do to automatically zgrep (in a bash script) last day .gz ??
Just wondering if there is a way to show the stats of the hard drive(s) in the computer mainly the current read and write transfer rates. Similar to the network graphs that show the Download and Upload speeds, but concerning the hard drive(s) in the computer. I know you can monitor the hard drive temperature, but I haven't seen anybody monitor the stats for the hard drive.
I have been looking for a script example of reading and writing to the parallel port's data, status, and control registers using bash. I see it done in pascal, tcl, etc. but nothing in bash.
I am trying to write a bash script to call from a terminal that will change the terminal title. I am using ubuntu 10.04. The script is meant to be used in the gnome-terminal.
Here is what I have:
Code: #! bin/bash echo "New title: c" read title echo "33]0;$titl07c" -e
[Code]....
it doesn't work
I think the problem has to do with modifying PS1 inside the bash so i tried this:
Code: echo `export PS1="[e]1;u@h:wa]${debian_chroot:+($debian_chroot)}u@h:w$ "` and it still didn't work.
In my tmp directory some logs are creating continue (with name logs.txt1, logs.txt2 up to 245). Some times these logs are creating continue within 1 or 3 second gap, now I want to write a bash script that continue monitor the tmp directory and if any time logs create simultaneously within 1 or 3 section gap it will alert me..( generally logs are create with the gap of 5 or 10 minutes duration or some time after one hours )
I have a bash script that checks for contents in a folder every 15 seconds and then acts on it's contents. This works great for the average size file however on very large files it starts acting on the file before it's completely written. Is there a facility in bash shell to get a file complete signal or such? here is trigger to launch a larger script.
Code:
#!/bin/sh while true do $HOME/bin/hpgl.sh >/dev/null 2>&1 &
I have a folder of 2 many files that the old ls just hangs.
I am trying to write some log files such as;
I don't mind doing one at a time, but I am just playing and even getting the listing I am not getting the date stamp, I have the following;
That does create the file, but all the files look like this;
So basically it's just sticking that ls inside the log file and not actually running the ls, so how can I use the above type to get files just created per year?
I am trying to write a bash script that sources another bash script. Essentially, I need a few lines to check to see if a certain variable is set. If not, I set it manually, and then source a scripts with that variable in the path. I wrote a test script to try it, but for some reason the last line does not work. Here is what I wrote:
#!/bin/sh source ~setupdir/setup.shrc #just a test, this line works echo ${#SETUP} # prints 0 if setup is not set, which it isn't if [ ${#SETUP} -eq 0 ] then SETUP="~setupdir" fi echo $SETUP # prints ~setupdir
I write a bash script to time some downloads from a server using ftp connection. ( something like: "time ftp 'options' ) I need to count the time for a list of files in a loop and output the result in a file.
I'm trying to write a bash script program in the Linux command terminal that will write to a fellow user and then continue reading down the program. this is what i have (kind of explains the idea too):
#!/bin/sh
clear echo "this is before the write command" write jcummins this message should go to jerry echo "the message didn't send and this string will not appear" echo "it appears it has stopped at the write command"
I am trying to figure something out as part of something else I am going to do. I was just wondering the easiest and quickest way to run a loop at the Linux command line which will make x amount of symbolic links when I need them.
I am using Debian 5.
I figure its something as easy as ~# foreach statement, then I just do a loop with the command to make a sym link.
I'm working on an application used for backup/archiving. That can be archiving contents on block devices, tapes, as well as regular files. The application stores data in hard packed low redundancy heaps with multiple indexes pointing out uniquely stored, (shared), fractions in the heap.
And the application supports taking and reverting to snapshot of total storage on several computers running different OS, as well as simply taking on archiving of single files. It uses hamming code diversity to defeat the disk rot, instead of using raid arrays which has proven to become pretty much useless when the arrays climb over some terabytes in size. It is intended to be a distributed CMS (content management system) for a diversity of platforms, with focus on secure storage/archiving. i have a unix shell tool that acts like gzip, cat, dd etc in being able to pipe data between applications.
Example:
dd if=/dev/sda bs=1b | gzip -cq > my.sda.raw.gz
the tool can handle different files in a struct array, like:
Is there a better way of getting the file name of the redirected file, (respecting the fact that there may not always exist such a thing as a file name for a redirection pipe). Should i work with inodes instead, and then take a completely different approach when porting to non-unix platforms? Why isn't there a system call like get_filename(stdin); ?
If you have any input on this, or some questions, then please don't hesitate to post in this thread. To add some offtopic to the thread - Here is a performance tip: When doing data shuffling on streams one should avoid just using some arbitrary record length, (like 512 bytes). Use stat() to get the recommended block size in stat.st_blksize and use copy buffers of that size to get optimal throughput in your programs.
I'm trying to make a automated build-script with bash but i keep getting different errors that I can't seem to figure out. Could anyone please tell me what's wrong with this package of build-scripts? I'm posting the main build-script and attaching the rest of the scripts in a compressed form. The errors mainly comes from the scripts in "/first_installation/usr/share/siem-live/init"
How can I iterate over all the files in the current directory to check for certain permissions? This is what I have:
Code: #!/bin/bash for file in *.tar.gz do if [ -r "$file" ] then echo "$file is readable" else echo "$file is NOT readable" fi done
But this only checks that the current user has read permissions for each file. I want to check that the group "others" has read permissions for each file. How can I do this? Is there a built in function to check if a file has read permissions for the "others" group? Otherwise, I thought I might be able to use this: Code: $ stat --format=%a file 744 And parse the output "744" and make sure the 3rd number is between 4 and 7 (since the octals 4-7 have read permissions for others).
I am relatively new to scripting, but I was wanting to open a firefox window from a bash script, but have it open, then minimize. In the script, I have a single instance of: firefox & but is there a way to minimize it, versus have it displayed on the screen? I was wanting the command terminal to remain visible and it can't since the firefox window is open in front of it. I looked all over the place, including the man pages, but to no avail. I can make the height and width changes, but no minimize. Either that, or to be able to bring the terminal window back to the front automatically.

I am not positive that this is the right subforum for this post. It is technically a programming question but I am not sure if this is the best place for bash scripting questions. Anyhow, I have been having trouble getting up in the morning. I am a pretty good morning person and once I am up, I am good to go. The problem is getting out of bed. Traditional alarms have just not cut it in the past; there is always an easy way to shut them off and go back to sleep.
Recentliesh, I decided to try to make an alarm script in bash that would be more successful in getting my lazy behind out of bed. I am a newbie bash scripter at best so my attempts have been very simple but have not cut it so far. Here are some examples:
[Code]....
The above script was the version of my bash alarm. It will not stop ringing until I input that ridiculous phrase. The big issue with this script was that I would input the phrase quickly and go back to sleep. It was however, much more successful than traditional alarm clocks. Another obvious pitfall was that even though control-c'ing the process would not work, the terminal could be closed and that would be the end of it. I'll get back to that issue. Here is my second attempt:
I have not been able to write bash to use a PID file to ensure no other instance of the same script is running! All three methods I can think of to see if the PID in the PID file is another instance of the script make the script exit with a return code of 1 but the same commands run at the command prompt work as expected.
The first attempt was:
Code:
The first attempted workaround was:
Code:
The second attempted workaround (with debug to make the following command prompt copy and paste meaningful) was:
Code:
Here's the command prompt session, testing with a stale PID file and then manually running the problem command and it behaving as expected:
Code:
This on Slackware64 13.1 which has bash 4.1.7.
In desperation I tried rebooting but the behaviour was the same.
I'm starting to like making bash scripts. It's kewl making creative ones. Right now I'm trying to make a bash script that will open up port 23 for a netcat connection. Once there's a connection, I'd like for the script to open up xmms and play a sound effect, as well as echo a txt file to the desktop saying that a connection was made at this specific time. When I execute the script, it stops exection at the first line. So far I have this:
I am trying to write a bash script that will extract a .cbr (.rar) file, traverse the extracted files in alphabetical order and rename them 001.JPG, 002.JPG, 003.JPG, etc.So far I only have this much to extract it:
I create a bash script that writes another bash file. But in the generated bash file I want to write a bash command in the file and not executing it.Here's my bash file:
Code: #!/bin/bash cat > ~/generateGridmix2data.sh << END
I have a set of bash scripts that I'm running that automatically build a set of packages for me and redirect their output into logs. Basically, I have a bunch of lines that are something like this: ${CONFIGURE_DIR}/configure &> ${LOG_DIR}/log or cd ${CONFIGURE_DIR} && make &> ${LOG_DIR}/log, etc.
This is supposed to make the entire process silent. However, sometimes with some packages some output leaks to my console (either stdout or stderr). I'm thinking that maybe the configure scripts/make are executing commands within new shell instances that don't inherit my redirect, or something to that effect.
Another reason for thinking this is that in another part of my script I detect errors when running make by testing with "if [ $? -ne 0 ]", and if the redirect leaks to my console and also the leaked output indicates that the build failed ("make: Error" and so on), then my $? test fails (i.e., it thinks that $? == 0, whereas a failed make should return a non-zero value). It's as if my original script can't "see" the results from child commands executed from later scripts.
I got the following task from my boss. I have to find out if there is some alternative tool for create reports from Squid except SARG. Now, we use SARG, but my boss told to me, that the main problem of SARG is, that SARG generate huge amount files, which cause problems during migration our servers. He told to me the following condition for change of current tool (SARG):
* standard package of Debian * generate less amount of files, optimal is to save reports to the database
So I would like to ask you if you know about some tool (I can not find some by google)... and the best would be if you told to me some practical experiences.
