Debian Multimedia :: Search File Contents From Gnome-Shell
Dec 16, 2014I have tracker installed, and when I use "tracker-search ..." from terminal, I can find files as expected. In particular, it searches within file contents, not just the titles.
I was hoping to have similar functionality directly from gnome-shell. I've found a number of extensions to do this such as: [URL] .... but none of them work (gnome 3.14, debian Jessie).
How to set up file contents search directly from gnome in Jessie?

General :: Shell Command To Find Newest File In Filesystem?
Apr 13, 2010I'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.

View 2 Replies View RelatedGeneral :: Display Specific Block Of Contents Or Lines In Output?
Apr 23, 2010Consider a situation in which you want to display only specific lines of contents from a file or of a command's output. Yes, we have head and tail commands. But, how to view all the lines of a file except the last one or vise versa when we don't know the count of lines in advance?
Consider this output:
Code:
[root@localhost ~]# ps au | grep bash
root 6316 0.0 0.0 4672 1440 tty1 Ss+ Apr22 0:02 -bash
root 20847 0.2 0.0 4672 1432 pts/0 Ss Apr23 0:12 -bash
root 21167 0.0 0.0 3920 660 pts/0 S+ 01:00 0:00 grep bash
Here, I don't want the last line (in italic) to be included in the result since the last line is due to "grep bash" in the devised command "ps au | grep bash". Well, we can rewrite the devised command:
Quote:
"ps au | grep bash | head -n 2"
But, again, here we are specifying the count of lines to be included. But, in the presented problem we don't know any count in advance!

Jul 1, 2011As the topic title states, I would like to know the preferred way of viewing the contents of a Berkeley DB file. The machine the file is on is running SuSE 9.3, with perl 5.8.6 and php 5.2.0 installed. (I'm not sure if stating that was necessary, but my understanding is that the more information I can provide you, the better. The purpose to this question is this: I have been requested to look into coming up with some form of Geocoding software for one of my company's clients. Specifically, I've been requested to look into trying to obtain Census tract/block information.
I discovered the Perl module Geo::Coder::US, which uses Census input (TIGERLine files) to create a Berkeley DB file, then reads said file to produce its own output. However, the output from Geo::Coder::US only provides latitude and longitude information.At the moment, my only interest is in popping the Berkeley DB file generated with the import script packaged with the Geo::Coder::US module. I'm trying to see what the contents of that DB file are, so I can determine if the information I'm after is even in there in the first place.

View 7 Replies View RelatedGeneral :: Errors Executing Shell Script: "command Not Found" And "no Such File Or Directory"
Jan 14, 2011A 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?
