General :: Shell Command To Find Newest File In Filesystem?
Apr 13, 2010
I'm relatively experienced with UNIX and Linux, but this has me thrown for quite a loop, and it seemed like such a simple question. How would I go about finding the newest file in a file system? I thought something like:
Code:
ls -ltr `find /usr -type f`
would work, but I seem to be exceeding the argument maximum for ls:
ksh: 0403-029 There is not enough memory available now
I thought something involving xargs might work, but I really suck with that command.

Is there a non-root shell command that can tell me if a user's account is disabled or not? note that there is a fine distinction between LOCKING and DISABLED:
LOCKING is where you prepend ! or * or !! to the password field of the /etc/passwd file. On Linux systems that shadow the passwords, this marker flag may be placed in /etc/shadow instead of /etc/passwd. Password locking can be done (at a shell prompt) via password -l username (as root) to lock the account of username, and the use of the option -u will unlock it.
DISABLING an account is done by setting the expiration time of the user account to some point in the past. This can be done with chage -E 0 username, which sets the expiration date to 0 days after the Unix epoch. Setting it to -1 will disable the use of the expiration date.
The effect of locking to to prevent the login process from using a supplied password to hash correctly against the saved hash (by virtue of the fact that the pre-pended marker character(s) are not valid output character(s) for the hash, thus no possible input can ever be used to generate a hash that would match it). The effect of disabling is to prevent any process from using an account because the expiration date of the account has already passed.For my situation, the use of locking is not sufficient because a user might still be able to login, e.g. using ssh authentication tokens, and processes under that user can still spawn other processes. Thus, we have accounts that are enabled or disabled, not just locked. We already know how to disable and enable the account - it requires root access and the use of chage, as shown above.To repeat my question: is there a shell command which can be run without root privileges which can output the status of this account expiration info for a given user? this is intended for use on a Red Hat Enterprise 5.4 system.The output is being returned to a java process which can then parse the output as needed, or make use of the return code.

In debian/ubuntu I want to:
a) Create a list of all the files in one directory tree
b) Do the same for a second directory tree
c) Compare the two lists such that, only the file NAMES are compared (i.e. just comparing the "file.txt" part so that "/home/folder/file.txt" == "/home/secondfolder/folder/file.txt)
d) Output a list of all the duplicates
How to do this using scripting languages or regex or something?

I need to remove a large binary file(PDF file) from a large log file which is generated daily.This is seriously hogging space on our servers.I need to remove the large PDF from the logs to make the logs smaller and manageable
I need to take out the texts (or binary file) between the strings
<my:PDF> and </my:PDF>
<applicationForm> and </applicationForm>
<image> and </image>
<extractedSignature> and </extractedSignature>
I am not sure whether sed utility can do this, these are large files and need to be pruned .I am not seeking logrotation advice just a script or command that can strip these large logs of texts between the characters above . I am not sure how to do this.These files are rather large.I am not sure how to achieve this with sed , tail, head , tr or any other facility .

Basically, I am trying to locate and copy the newest .json bookmark backup in my .mozilla/firefox/w987sdg9.default/bookmarkbackups directory.
I tried this
Code:
ls -t ~/.mozilla/firefox/b1ahb1ah.default/bookmarkbackups/ | head -1
which does return the newest file, but only the filename itself. I found readlink, but I haven't gotten that to output a full path which I can then feed to copy. So, it seems to me that find might work well here, and I know how to find based on absolute dates, but not relative.

I am trying to run a cron job as an oracle user. I put the user in the cron.allow file but it still won't run. Other users are able to run a cron job though. I think it's the way the oracle user was created and I wanted to recreate it. However it owns a lot of other file systems as well as the database. Is there a way to recreate or reset the oracle account without impacting what is currently in place?

I am trying to find / write a shell script that will go through a file organized like this (but with thousands of lines)...
93,5.00,"contig00002",169,83,"jgi|Brafl1|100379|fgenesh2_pg.scaffold_359000019"
579,1.00,"contig00003",3,380,"jgi|Brafl1|114745|estExt_fgenesh2_pm.C_1200006"
450,5.00,"contig00007",2,352,"jgi|Brafl1|274326|estExt_GenewiseH_1.C_8420008"
...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.

I'm working on a bash script that will go through a directory, find the sub-directories that have been created since the last time the script ran, count the results, and output that integer (will most likely be '1' or less per each instance run) to a file. Give the circumstances, my previous (and very limited) experience with bash is not sufficient for me to pull this off. since it probably has bearing, is that my mail server stores files that it flags as viruses in a folder. It creates a sub-directory for each virus that it quarantines .I want to count those subdirectories and graph them with MRTG. Hence the script. I'm going to post what I've got so far and the purpose of it, because I'm told I have a very odd and efficient way of doing scripting.
[Code]...
But then it dawned on me that it wouldn't work because I would have to not count the directories that have already been counted and count the ones that have not been counted. Given that the purpose of this is to generate a graph about every 5 minutes, using find won't work because, to my knowledge, that will only find things based on whole day values, I need it almost down to the minute.

A colleague gave me a shell script ("dti_motion") which needs to be run from the directory containing all the files it works on. I want to run the same script for several different directories. But I don't want to have to cd into each directory, run the script, wait for it to finish, and then cd to the next directory (there are 52 to do altogether).
So I wanted to write a very simple script that will cd to each directory and perform the script there, before going on to the next one. My colleague's script ("dti_motion") is stored in my home/bin/ and is executable. My home/bin/ is in my path, as verified by echo $path. When run from a directory containing the necessary information, the dti_motion script works perfectly well. I wrote an extremely inelegant script called "dti_motion_do_all" which is also stored in my home/bin/ and executable:
#!/bin/sh
#Get motion information for each subject, using Mark's script, called dti_motion
cd /imaging/cr01/PD_DTI/C_10/12x5
[code]....
I know there will be more elegant ways to write this script with loops, rather than simply using cd, but for the moment, I just want this to run, until I have learnt to use loops properly. how to correct either of those "command not found" or "no such file or directory" errors, given that both the original dti_motion and my dti_motion_do_all script are in my /home/bin/ (which is on my path) and both scripts are executable?

I'm logged into a server through the CLI and did a df -T and confirmed all my volumes are ext3. but when I do a tune2fs -l /dev/sde it tells me
tune2fs 1.39 (29-May-2006)
tune2fs: Permission denied while trying to open /dev/sde
Couldn't find valid filesystem superblock.
I don't have root access on the server, but is that why it's complaining, or is my syntax incorrect?
