General :: Write Shell Script To Check The Modified Date Of A File ?
Jun 17, 2011
I have two linux servers, they are backup together.
1. Server 1 have 3 files with name: file1, file2, file3 in the path: /etc/sysconfig/network-script/.
2. Server 2 have 3 files with name and path are the same as server 1.
- How to make a script to copy 3 files at server1 to overwrite on server2. But before overwrite, this script will check and compare the last modified date of these 3 files(on server1 and server2). if the modified date of file1, file2 or file3 on server1 is newer than 3 files on server2 then overwrite process will do, if not, will do nothing.
- see my script as below: it works find now but just overwrite. not check last modified date.
I need to get the modified date on a file in linux to use in a script.I tried using 'ls -l' on the file, but this caused problems when the date turned from a single digit into a double. The reason for the problem was because I was parsing the result string on spaces.How can I get the date of the last time a file was modified so I can use it in a script? For example, if a file was modified on 1/11/2010, I need the 11.
I am a novice to the shell script. In my system from db server the log files are enerating with the name log1.txt,log2.txt..... It is capable of keeping 10 files at a time in dir called /db/sis/log1.txt. I want to copy the log1.txt to another directory when ever it generating by attaching the time stamp to it for the back-up purpose. this files will be there for a period of 24 hours. after that the back-up dir should be cleared and it start copying again the fresh file from the same dir.
I need a shell script that will add the users name and date to a file when the user has modified the file, these files are within a group and only accessible to this group. But we need a way for people in the group to know who and when the file was last modified.
I am new to Scripting. I am trying to find out particular file is modified in last one hour or not in script and then if that file is modified in last one hour i need to copy that file to another directory.Can any one please provide me how to check the file is modified in one hour or not?
Prior to making a fresh install of 10.04, I made a back up of all my documents by copying them to a NTFS partition. I did this my selecting files in File Browser, then right clicking and selecting the Copy command.
When I came to move the files back after the fresh install, I was mortified to find that all the file modification dates had changed to the date I copied them! I've lost all the original file dates, which was the principal way I sorted my files. I guess there's no way of getting it back? It seems that Linux does not store File Creation dates either so I'm stuffed.
so I was wondering how I could do a simple find which would order the results by most recently modified. Here is the current fine I am using. (I am doing a shell escape in php, so that is the reasoning for the variables. find '$dir' -name '$str'* -print | head -10
How could I have this order the search by most recently modified. (Note I do not want it to sort 'after' the search, but rather find the results based on what was most recently modified)
I need to know all files modified within a date and time range.E.g: All modified files between 20 April 2010, 1100-1200 Hrs."find / -mtime +10 ! -mtime +11" :: this i found for date but how to include time as well.
I want to write expdp output in a text file using a shell script
If i write like below:
It will write whatever is there in log file to text file
But, sometimes export fails with out start taking export (without generating log file) because of job already exists error. such times, we dont know about that error until we check manually... so i wrote like below:
But still it is not writing anything in to text file using above stmt...
I am actually modifying someone else's script and The original script rotated image files to the left but it changed the "modified date stamp" which is something I didn't want.
I clone my entire notebook hdd once a month to a USB drive with an identical disk once a month using dd. I would like to find a way to automatically or manually do incremental backups at shorter intervals.
The first problem is that my incremental backup drive is not the same as my full backup drive (which is my clone). Is there some way to backup or copy all files on a document partition modified after a certain date?
The second problem is that my document partition is NTFS-3G. I guess this could be done pretty easily using "dump" if I stored my docs on ext. [I don't because I want to make sure that my docs are accessible from any machine (say in an Internet cafe) should my MacBook die and I need to rip out the hard drive and run to do my homework on another system; that is why I keep my docs on my Vista partition].
I want to write a shell script which will simultaneously collect OS user information and write in an individual text files.Can anyone tell me the syntax of the script.N.B. The user name will be mentioned in an array within the shell script.
Sequentially number files based on date modified (rename cli)
I'm almost done a larger script which takes all the pictures in a folder, converts it to video, and emails it to me. Everything worked fine until I realized the picture filenames weren't always starting at 1, then ffmpeg chokes.
I have a bunch of files in a folder which I need to rename to:
I don't want to install any additional packages and I'd like this to run in a single command if possible.
If not possible, then a bash script would work too.
I am using CRON to create a new, blank file, every minute, in a specific location on my web server. After web searching, and reading man pages, I get the impression that the following command is supposed to work:touch /home/mydomain/var/folder/attachments/`date +%H%M`.txtThis should give me a new file with a file name that is the current hour and minute.However, when executed, the CRON mailer reports:touch /home/mydomain/var/folder/attachments/`date +/bin/sh: -c: line 0: unexpected EOF while looking for matching /bin/sh: -c: line 1: syntax error: unexpected end of fileSo, it looks like shell is seeing the plus (+) sign as an EOFObviously, nothing get created.What would be the easiest, single line command to create an empty file, at a given location, with a time based file name
I'm new to UNIX scripting; I�m stuck with the following I have an Oracle SQL script that takes three parameters
1- File Name 2- File Path 3- File creation date
Under UNIX I have a folder where files will be placed frequently and I need to upload those files to Oracle, what I need is a UNIX script that can do the following
Loop through Directory "/home/applmgr/snktmp" Picks only files Pass the file name to parameter &1
[code]....
Is the above possible? I already knows how to call the Oracle Script from UNIX Im only stuck on writing the UNIX part where it List the files attribute(name,path,date) and store them to parameters ,Looping until the last file in the directory If the above is not possible,then how can I create the below from the command line
I have a number of text files throughout my /home/pjs/Documents directory tree that have execute permissions set. Almost all of my file names have spaces in them. I am trying to write a shell script that will look at each file in my Documents directory, find the ones that have execute permissions set, and run the command chmod 644. Of course, I don't want the command run on the directories.
The following script *doesn't work*, but might serve to illustrate what I am trying to do:
#!/bin/bash for x in "$(ls -R)" do if [ -f "$x" ] && [ -x $x ]; then chmod 644 "$x" fi done
I want each file and directory name to be placed, one by one, in the variable $x, and then tested with the "if" conditionals.
The first problem seems to be that, although the command "ls -R" does produce a complete list of the files and directories I need, they are not placed, one by one, in the variable x like I want them to be.
Also, I think I should use the shift command so that the option -R doesn't get included as one of the values of the variable $x, but I can't figure out where to put it.
I have a file that's supposed to be growing in size 24/7. I want to check every 10 minutes via cron that it's actually growing. If not, send an email. Does anyone know how to write a script to do that?
I'm trying to write a script that searches my files and lists them by date. Can someone point me in the right direction? I've been looking through the books that i have but i'm just not finding the right commands to search dates.
-Qjackctl has a config file which is modified each time QjackCtl is shut down. This means that whatever preset is in use when QjackCtl closes is written into the QjackCtl config file as the DEFAULT PRESET, for the next time QjackCtl starts (or at least this is how I understand it).
-I want to edit a specific line in the QjackCtl.config file, which specifies the DEFAULT PRESET. Obviously its easy to do manually, but I want to do it using a shell script which runs automatically on StartUp so that QjackCtl starts every time with the same DEFAULT PRESET, NOT the last one used.
-Unfortunately Im not at my Linux system right now (which is KXStudio/Kubuntu), but I believe the QjackCtl.config line looks something like this: DEF_PRESET=alsa (where alsa is the name of the preset)
PRESET1=alsa PRESET2=firewire
I want a shell script which changes the line DEF_PRESET=alsa to DEF_PRESET=alsa, even when it may currently exist as DEF_PRESET=firewire due to occasions when firewire was the active preset when Qjackctl was last closed. I notice that the application in KDE that enables the user to set which applications open automatically on StartUp also allows the user to select shell scripts.
Ive done some research, as a beginner, and Im led to believe I might need to use AWK and/or CHMOD. I could have a go at writing a shell script but Im always wary about experimenting with StartUp scripts/operations because obviously if I get it wrong and make my system unusable, then because its going to run first thing on each boot, Id have great difficulty disabling it.
...and check the region of each line between the second and third pipes (the 6-digit numbers) against the values in the first column of a separate text file in CSV format like this...
274326,"Wnt family of developmental regulators" 114745,"FOG: Hormone receptors" 100379,"Transcription factor tinman/NKX2-3, contains HOX domain"
...and when they match, replace the value to the right of the third pipe (e.g., fgenesh2_pg.sca...) with the value in the second column in the CSV file associated with that number.

Code: #!/bin/bash while [[ -n "$1" ]]; do #if a file and not a dir if [[ -f "$1" ]]; then
#the images that I copy from my cell phone don't have exif headers #so I am using the -mkexif switch first to match the exif information #to the "created date" in the .jpg file. jhead -mkexif "$1"

It's important to note that the original script, before I made any edits, did not have this quirk whereas I needed to "touch" the file to get it to orient itself correctly. The 'original' script is in black; my additions are in blue.
I have a Redhat server that it is allowed rcp file from remote server, it is strange that after I modified the .rhosts, the server is no longer to accept rcp file , even I use other user to rcp files , the error is still "Permission denied", can advise what is wrong ? what daemon that I can try to restart ?
I am trying to write a shell script in order to automate the process of uploading a file onto an FTP server using the built in FTP commands in ubuntu server (lucid). In order to connect I can use the following:
Code:
ftp wsbeorchids.org.uk Name (wsbeorchids.org.uk:danielgroves): USERNAME Password: PASSWORD
In need to pass my username and password in when prompted the prompts. How should I go about doing this? I have tried echoing the values without success. Please not that I am something of an amateur with scripting.
