I have no previous programming experience. I know this question has been asked before or the answer is out there but I, for the life of me, cannot find it. I have searched google for hours trying to figure this out. I am working on a Red Hat Linux computer and it is in bash.
I have a directory of files 0-500 in /directory/.
They are named as such,
/directory/filename_001, /directory/filename_002, and so forth.
After running my analysis for my research, I have a listofnumbers.txt (txt file, with each row being a new number) of the numbers that I am interested in. For example,
015
124
187
345
412
A) Run a command from the list of files the files from the list of numbers? Our code looks like this:
g09slurm filename_001.com filename_001.log
Is there a way to write something like:
find value (row1 of listofnumbers.txt) then g09slurm filename_row1value.com filename_row1value.log
find value (row2 of listofnumbers.txt) then g09slurm filename_row2value.com filename_row2value.log
find value (row3 of listofnumbers.txt) then g09slurm filename_row3value.com filename_row2value.log
etc etc
B) Move the selected files from the list to a new directory, so I can rename them sequentially, then run a sequential number command?
Thanks.
First, read the list of files into an array:
readarray myarray < /path/to/filename.txt
Next, we'll get all the filenames based on those numbers, and move them
cd /path/to/directory
mv -t /path/to/new_directory "${myarray[#]/#/filename_}"
After this... honestly, I got bored. Stack Overflow is about helping people who make a good start at a problem, and you've done zero work toward figuring this out (other than writing "I promise I tried google").
I don't even understand what
Run a command from the list of files the files from the list of numbers
means.
To rename them sequentially (once you've moved them), you'll want to do something based on this code:
for i in $(ls); do
*your stuff here*
done
You should be able to research and figure stuff out. You might have to do some bash tutorials, here's a reasonable starting place
So This is related to my other two posts. Im dealing with extracting text from a text file and analyzing it and I've run into some problems. For A while I've been using a method that sets all the text between two other strings as a variable, but here is the situation I have. I need to extract the speed (numbers) from the below string: "etc...,query":{"ping":47855},"cmts":...etc. The problem is that the text cmts sometimes changes to something else so really I need to extract all the numbers from this:
,query":{"ping":47855},"
One more thing that makes this difficult is that the characters }," Are all over the file. Thank you for helping me! -Lucas EDG Programmer.

By the way, the reason things change is because it looks at info from different servers
Very similar to ther answer I gave you to your first question:

I'm looking to build a simple program that will simply modify existing output files from an other program so I don't have to open the program and enter a bunch of data the long way. This program is very specific to my domain and has an extension named .wcc. However, when I change the extension of one of these output files to .txt, I get half gibberish :

There are also musical notes and perpendicular signs which I can't copy paste here. I can sorta read the text, but still not enough to make modifications via txt file. What type of file could this be? Is it even possible to do what I'm trying to do? Thanks!
I am surprised that you are trying to open a .wcc file as a text file (it's contents - as you will see - don't lend themselves to being converted to such a file type); however, the attempt to open the file as a .txt file seems to be specific to your domain.
I noticed part of your question is as follows: "What type of file could this be?"
You are right in thinking that the .wcc file is a rather obscure file type - we don't think about that file type a lot (or are not conscious of it existing). A .wcc file is a WinCam 2000 Cache file that allows WinCam 2000 movies to be previewed in the slide browser - these were often generated by older WinCam 2000 screen recording and editing programs.
Again, the file extension is very rare these days (a Google search only returns ~700 results). But, it appears you have a program that is producing the file, which - as you are saying - "is quite specific to your domain". You may be out of luck with regard to opening them for modification purposes.
Supposedly, you can covert .wac files to .wav files, which are much more relevant to today's technology (and definitely alterable from code); however, without knowing the purpose of the file, e.g. what you are trying to do with the file domain-side, I can't say that this will suit your needs.
Also, the above comments are "correct": changing a file extension will not convert the file to the file extension type. Typically, converters - like a simple software - are needed to convert files.
I have another puzzling problem.
I need to read .xls files with RODBC. Basically I need a matrix of all the cells in one sheet, and then use greps and strsplits etc to get the data out. As each sheet contains multiple tables in different order, and some text fields with other options inbetween, I need something that functions like readLines(), but then for excel sheets. I believe RODBC the best way to do that.
The core of my code is following function :
.read.info.default <- function(file,sheet){
fc <- odbcConnectExcel(file) # file connection
tryCatch({
x <- sqlFetch(fc,
sqtable=sheet,
as.is=TRUE,
colnames=FALSE,
rownames=FALSE
)
},
error = function(e) {stop(e)},
finally=close(fc)
)
return(x)
}
Yet, whatever I tried, it always takes the first row of the mentioned sheet as the variable names of the returned data frame. No clue how to get that solved. According to the documentation, colnames=FALSE should prevent that.
I'd like to avoid the xlsReadWrite package. Edit : and the gdata package. Client doesn't have Perl on the system and won't install it.
Edit:
I gave up and went with read.xls() from the xlsReadWrite package. Apart from the name problem, it turned out RODBC can't really read cells with special signs like slashes. A date in the format "dd/mm/yyyy" just gave NA.
Looking at the source code of sqlFetch, sqlQuery and sqlGetResults, I realized the problem is more than likely in the drivers. Somehow the first line of the sheet is seen as some column feature instead of an ordinary cell. So instead of colnames, they're equivalent to DB field names. And that's an option you can't set...
Can you use the Perl-based solution in the gdata instead? That happens to be portable too...
