General :: Convert A Large Number Of File Types From None Standard To Text?
Sep 28, 2009
I have on my windows machine several hundred files that are a format of .nc .ncs for a CNC machine. I need to convert them to txt which is something as easy as opening in notepad and then saving as .txt but there are so many that this kind of action would take way too long.
The reason I am writing the linuxquestions is because I would feel more comfortable in loading a live CD and using some sort of terminal command to do this than I would to download one of the many "freeware" type programs I have found for windows (even more so since I have had a root kit before and had to start all the way over to get rid of it).
I need to know:
1. Is this possible to do with the terminal without super advanced knowledge.
2. Can one please point me in the right direction; something to read or an example

I have a large number of log files, on a linux box, I need to cleanse sensitive data from before sending to a third party. I have used the below script on previous occasions to perform this task, and it has worked brilliantly (script was built with some help from here :-)
#!/bin/bash
help_text () {
cat <<EOF
Usage: $0 [log_directory] [client_name(s)]
EOF
[Code]...
However, now one of our departments has sent me a CLIENT_FILE.txt with 425000+ variables! I think I may have hit some internal limit. I have tried splitting the client file into 4 with around 100000 variables in each, this still doesn't work. I'm loathe to keep splitting though as I have 20 directories with up to 190 files in each directory to run through. The more client files I make, the more passes I have to do.

I'm trying to manipulate a large text file full of records (metadata - one complete record per line). I need to delete every line on which certain words appear - there are five different words, all pretty simple all-caps strings with occasional whitespace. I tried using grep -v, which worked a treat, but only string-by-string. Ideally I'd like to run this as grep -v -f, where the file targeted by the -f contains the strings I need to match in order to delete the lines they're in.
i.e. grep -v -f filecontainingSTRINGS.txt targetfile.txt > outputfile.txt
When I try this, however, I don't get any matches - or more specifically, no changes are made in the output file. It works fine if there's only one string in filecontainingSTRINGS, but it doesn't work if there's more than one (I'm using newline as the delimiter). (Also my machine doesn't recognise /usr/xpg4/bin/grep - no idea what that's all about!)

I'm trying to isolate a number from a text file using sed. The text file looks like this:
-GARBAGE-GARBAGE-GARBAGE- Number of frames: 183933 frames Codec -GARBAGE-GARBAGE-GARBAGE-
I tried the following:
Code:
sed "s/^.*Number of frames: //g; s/ frames Codec.*$//g" "info.txt" > "frames.txt"
Strangely, it only seems to be stripping off the end, but not the beginning, like so:
-GARBAGE-GARBAGE-GARBAGE- Number of frames: 183933
I'm obviously not using the command correctly, so what am I doing wrong?

I need to be able to convert HTML email messages saved as text files (.eml or .msg) to PDF documents, one PDF per email, retaining formatting and images.
Are there any Linux tools that will allow me to do this from the command line (so it can be scripted)?

Basically, I have a selection of .rdp shortcuts to various machines, but they are considered the file type "plain text document (text/plain)" so if I change it to open with to tsclient, all of that file type opens with tsclient. And if I change it to gedit, all the rdp files open with gedit. Is there a way to create a custom file type dependent on the extension rdp, or is there a way to set tsclient to open by extension rather than filetype?

I checked the 'Run executable text files when they are opened' option in Nautilus preferences. I have noticed that files such as .sh and .bin launch by simply clicking on then (which is great). However I have also noticed that an ordinary .txt and .html file must not be marked as executable in order to launch it in Gedit and Firefox respectively via clicking. Otherwise you must right click and open with every time. What file types need to have execute permissions? What file types never need to have execute permissions?

I need to search a text file for a string of numbers which are different lengths, and always are between number=" and " like:
number="1234567890"
number="22390"
I need to grab those numbers and pipe each one to a line in a file. I've already tried something with awk and that didn't seem to work.

In order to make this conversion I have to use a text editor. This is tedious. Is there an easier way to do it, like some program I can run from the Linux or OSX terminal?

I want to convert many text files(copied from windows workstation) into utf-8 encoding file. Yes, iconv is available for it. However, I have to give source file encoding at the command line parameters! The problem is, at most case, I am not sure the source encoding of it. And, I also want to use a script to convert many files recursively.

I am on Ubuntu 11.04 and using Libre Office 3.3.2 to compose new documents and am saving them using .doc, .ppt and .xls files. (due to having to share them with others who are on Windows systems)
I have a lot of doc files and I need to search for text INSIDE these files. I am perplexed with the fact that no search tool is able to search for text INSIDE these file types. "cat" can display them of course, but grep is not able to locate text INSIDE these file types. I even tried to save a .doc file as an .odt file, but no luck. The Applications>Accessories>Search for Files does not search INSIDE doc, xls or ppt with the option "Contains the text".

I'm using Grsync and I want to be able to plug in any drive into my laptop and run rsync on it to back up all the user documents on there to another external hdd and to exclude everything else. Working on the principle that user documents don't always appear where we'd expect I want rsync to look through the whole drive and filter what it backs up by file type. I am only having partial success, however.
I am using the 'filter' option in the 'additional options' box. I am using the command
Code:
filter='merge /home/tim/Desktop/filter'
and I am attaching the filter file I have written. (I have added the .txt extention to upload it).
I have tested this script on my home folder and here's what's going wrong. Rsync will copy the entire directory structure regardless of whether there are any files to be copied over in those directories. I am also getting only some file types getting included and not others. .odt and .ods files are copied, for instance, but not .doc or .rtf.

I have a large text file with three columns. I'm trying to write a PERL script that splits the file up based on the value of the 3rd column. So every time the third column reads 0, a new file is created and all the data up until the next 0 is found is written to that new file. This should happen over and over until the initial file has been entirely split up.
ex data:
000
2024
2243
2143
96962871
97972878
000
2034
3034
3352
So with the data above, the file would be split into two files:
data_1.txt would contain
000
2024
2243
2143
96962871
97972878
and data_2.txt would contain
230
2034
3034
3352

I need to do some text file manipulation which I think should be done with standard commands in BASH. I'm looking at comma seperated text files (stock market data). It comes in the form of date, stock code, open, high, low, close, volume. What I need to do first is move all data with same stock code sequentially into individual files.
While doing this since the stock code will now be the file name I need to remove the stock code. Next I need to filter out overlapping data from different files with the same date. ie. where two files contain the same date on the one line only one line will be added to the combined file. I think there must be a tutorial out there for basic text manipulation like this, I just haven't found it yet.

I understand that chroot is usually used to provide security, however, for my issue, security is a big don't care. I am very new to using chroot and don't fully understand how the chroot'd env works.
problem: Trying to use a vendor supplied cross compile environment. The environment runs as a chroot'd env and works just fine. I have a large number of additional modules that I wish to compile in the chroot'd environment. FYI, these modules are also (succesfully) compiled for other targets not using chroot'd env's. Copying the source files into the the chroot environment is not an option (don't have hours to wait for copies to finish and it would break the make system). Having them live in the environment is also not an option (the chroot build is a tiny part of the build process and we cannot revamp our entire source tree to accommodate it).
I am looking for a way to have the compiler in the chroot'd env have access to a path that is outside of the env and typically higher up in the same path that holds the chroot'd env. I have tried soft links (they don't work as expected). Hard links only work for single files and there are 10's of thousands of files that would need to be linked. I am not sure how I would go about exporting the additional files and then mounting the exported files in the chroot'd env (or if that would even work).

I am looking for some source package which will convert plain text file to html file without using perl.
I mainly need to do this on an ARM platform, so if I get sources I can cross compile it.
