I have used "FILENAME="`TZ=$TZ+24 date +%y%m%d`" in a bash script that run in openbsd. What my script does is to changes a file name to "yesterdays date". I tried to use it in a script that runs in debian but it doesnt work. Is there any other command that i can use in debian?
View 3 RepliesI need to be able to compare a file date with system date and delete files older than 30 days.
the file name is basically
error_log.03222011
of course the extension is the date the file was created.
Oh and before i get hammered I looked everywhere but am unable to make sense of what I found.
I need to convert strings in the format YYYYMMDD to dates so I can perform date arithmetic.
View 4 Replies View RelatedI've recently inherited a bunch of files at a new job and am trying to figure out some of the problems that have constantly popped up. The one i'm getting a huge headache with results from a bash script that is supposed to change a date format from a client populated txt field to one we want defined a certain way. Everything in the script works fine, except that one function. Below is the line i'm trying to manipulate, with date examples.
sed -e 's/.0000 EA/ EA/' -e 's/ 01012010 / 01-JAN-2010 /' -e 's/ 12312011 / 31-DEC-2011 /'
The one caveat is that the first date is non-static and changes daily. It is, however, always the current date. If it helps, the second date will always be a year away from the first date.My idea was to pull the current date via perl's DATE function, but...how to do it, and calculate a year away without throwing the rest of the bash script off? Any help would be appreciated. I'm sure it's a simple solution but i know absolutely nothing about these scripts and how they were written.
I need this script but I don't know how to do it I have one folder with several folders inside.On each folder a have one MKV or AVI file inside...What I need is a script to change the "modification date" of each folder to the "modification date" of each MKV or AVI that the folder has inside.

However, yesterday's upgrade (I run dist-upgrade roughly every day or two) I've been experiencing some very low FPS rate - about 150-250 according to glxgears. My gfx card is a bit old - Radeon Xpress 1100 (200M).
Xorg.log and syslog are both fine. I've tried forcing the "radeon" video driver in xorg.conf as well as the automatic "ati" value without any effect.
It could be a bug, or it could be something resulting from the upgrade of any of the packages.

View 6 Replies View RelatedI would really like to preserve a file's original modified date and pass it back to the file as the same attribute after a script has worked on it. I get a lot of JPEG files from different places on the Net which I either turn around and upload or burn to disk, and having the "original" date of either download or last mod in a graphics app would be for me, in the long run, a lot more helpful when deciding, for instance, which files to "recycle" or pass on backing up more than once.I've tried doing this on my own every now and then. Where I run into problems is that it appears "stat" and "date" use different formats for date information, and I can't seem to puzzle out how to "translate" one to the other satisfactorily for the latter command.
Just to give an example:
stat foo.jpg |grep Modify gives me
Modify: 2010-07-12 06:28:56.890625000 -0400
Passing that string as-is to date foo.jpg, I get the errordate: unknown option -- 0 and the usual semi-courteous suggestion to Try 'date --help' for more information.Somehow my TexInfo database got screwed up somewhere along the line and info dategives me the short article on date input formats, not the full documentation for the command
Is there any other short/easier and smarter way to do the following in Linux? code...

I am trying to use the date command in a simple bash script as below:
#!/bin/sh
this_date=`date`
echo "The date is $this_date"
This script seems to work only if a surround the command with the `` characters, which I copied from another script. Can anyone tell me why this is, and how I can insert these characters from my keyboard,which only has normal quote and double-quote characters?
This might well be a case of "I've been looking at terminals for far too long", but here goes. In a bash script I'm writing I'd like to get the current minute of the day. Since date doesn't have an in-built format string for that, I thought I would do:minute of day = 60 * hour of day + minute of hourHowever, when the clock rolled around to 12 / 0 the value disappears from the variable. Viz:
Code:
hour=$(date +%k)
echo "hour: $hour"

You are probably using systemd (check it with ps --pid 1) and therefore /etc/init.d isn't considered for autostart. Here can you find some information about systemd and autostart [1]. As far as I know systemd isn't intended to start applications with systemd. I recommend you to use the autostart feature of your window manager or desktop environment or at least the .xinitrc.

I am writing a script that calls a program which writes a lot of lines to stdout continuosly. If the last line in stdout has some regex, THEN, certain variables are updated. My problem is that I don't know how to do that.
A simplified example would be (it's not my exact case, but it I write it here to clarify): suppose I issue a ping command (which writes output to stdout continuously). Every time that the response time is t=0.025 ms, THEN, VARIABLE1=(column1 of that line) and VARIABLE2=(column2 of that line).
I think the following code would work in awk (however, I want the variables in bash and I don't know how to export them)
Code: Select allping localhost |awk '{ if ( $8 == "time=0.025" ) var1=$1 var2=$2}'
In the previous code, awk analyzes each line of the output of the ping command as soon as it is created, so the variables $var1, $var2, ... are updated at the appropriate time. But I need the "real-time" updated values of $var1, $var2 in bash, for later use in the script.

I need show the number of process per user, and after the date of the oldest process per user also.
With "ps -eo user | sort -u" i get all users that are running any process. And with "ps U username | wc -l" i get the number of process that the user "username" is running.
But how can i merge both commands for do what i need? Like a FOR or something like that. There is any method of make a FOR using the list that i get with the first command?
And then for show the date of the oldest process.. with "ps U username | sort -k 4" (4 is TIME field) i can show the process of the user "username" sorting they by time. But how can i get the date of the process takes longer running?? I can get only the time, but no the date.

How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!

I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?
After yesterday system update the x server won't start up anymore. It locks immediately with blank screen leaving the computer unresponsible until hard reboot. I hat to once again go with the "vesa" driver, as I mentoined earlier in another thread it is a life saver, always works. My video card is integrated Radeon HD3250 - video driver was fglrx from ATI itself. "radeon" driver now reports that modesetting is not supported and will not load with EE-type X server error.
Anyone else experienced this? Are there any changes in the most recent X server that once again break compatibility with the official ATI driver?
Say I have a line like such:
Code:
today 2010 Feb 21 test10, 12AM
How would I print everything AFTER "2010 Feb 21 "?
What I thought to do so far is to set a variable to the format used in the string like so:
Code:
date="$(date +%Y %b %e)"
So I know I have to use either awk, sed, or perhaps bash substrings to work with the variable $date, but as to how, I'm drawing a blank.
I would like to get the filename (without extension) and the extension separately. The best solution I found so far is:
Let FILE="thefilenameofsomefilesfor_instance.txt"
Code:
NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.
