I would appreciate help with how to extract the date and time from at command jobs. From what I can tell, the date and time is embedded in the file name (/var/spool/atjobs).I'd be using this information in a (bash) shell script.

I'm trying to find a proper command to move a certain set of files according to date/time range. I am thinking that the command should be something like:
Code:
ls -l | grep 'date/time range' | mv /folder
I need to extract the absolute directory from the type command when I pass it a program name. E.g.
Code:
>type cat
cat is hashed (/bin/cat)
There is one other case (I believe):
Code:
>type lpr
lpr is /usr/bin/lpr
I thought of using regex, but it returns the whole line, not just the match. In addition, there is no option cited in the man page for type that returns just the command directory.
Note: this is part of my solution to a programming assignment in bash shell scripting.
Why is the output of the following commands different?
root@vmi2115:/var# hwclock
Sun 26 Jun 2011 01:21:38 PM CEST -0.273230 seconds
root@vmi2495:/var# date
Sun Jun 26 15:21:39 CEST 2011
root@vmi2115:/var#
And can I change the current time on Linux?
rpm -qa --last lists all rpm with date and time. But I want to sort the list by date, with earlier rpm displayed first. So it needs pipe, rpm -qa --last |

View 2 Replies View RelatedI've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.

I wrote a hack script that outputs the following every so often: Code: 01/04/11 10:33:02: 97,1413,1447,2860 I must leave the data format the same --but I want a special number from it. In this case it's 97 and it's always going to be the first in the 4 columns of comma delimited items. I can extract with this:
Code: cat datafile | awk -F" " {'print $3'} | awk -F"," {'print $1'} But that's really sloppy. Can someone point out a better way of doing this (with awk) and tell me why?
How to use the date command to display, for example, 10-Mar-2010 01:01:53? What's the format string?
View 2 Replies View RelatedI am trying to extract just a few files/folders from a Time Machine backup, but can't seem to find them. The drive is automatically mounted in Ubuntu, and am able to access after enabling view hidden files, the HFS+ Private Data Directory. But that is a jumbled array of thousands of numbered folders, with each taking a fair amount of time to open on this aging Dell running 10.10.
I've tried running the standard Places - Search for Documents, with 'Show hidden and backup files' enabled, but that won't pull up any of the search times I'm going for (and seemingly won't find anything at all on the drive). So, is there any way to decipher the directory tree so as to be able to access this data from Ubuntu? Or perhaps a file embedded somewhere in there that lists out the original structure, so that I can use it as an index to see what number correlates to what originally named folder?
I need to pipe the output of date command, to form a command like this:
mycommand -f 20110721
where 20110721 is current YearMonthDay.
I am doing some NSCA log parsing and I want to get an output like this:
2011-Feb-18:11:00:07
2011-Feb-18:11:00:07

2011-Feb-18:11:00:08
2011-Feb-18:11:00:08

I have tried this, but it treats the entire output as a single line, then plops a timestamp on the end (I think):
Code:
sort -b -k4.9,4.12 -k4.5b,4.7Mb -k4.2,4.3 -k4.14,4 foo.log| date -j -f "%Y-%b-%d:%T" "+%s" "`awk -F '[ [/:]' '{print $7"-"$6"-"$5":"$8":"$9":"$10}'`"

View 9 Replies View RelatedI'd like to change a files modification date "only" without changing the time. I'm aware of the 'touch' command but is seems like it only allows changing both the date and time, and not one of them. Any ideas on an easy way to change a file's modification date without also changing its time? (I have a long list of files and thus would like to run one to command to change them all)Example: Change a file's (month) timestamp from "2010-09-23 11:59:23" to "2010-10-23 11:59:23"Background: I accidentally set the wrong month on my camera and ended up with all photos having a modification timestamp with the wrong month.
View 3 Replies View RelatedI 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.
