General :: Sorting A File With A Variable Name?

Jun 27, 2011

I am trying to sort a file, so I can compare it to another file later. I am storing the file name in a variable called curMo. I then call sort $curMo and it hangs for a very long time and I have to quit the process. why this is not working or how to make it work?

Here is part of my code:

#sort this file for this Location
sort -u $curMo -o $curMo.sorted

Programming :: Sorting A Dictionary File?

Nov 1, 2010

I have this dictionary file that has this format:

SUBSTITUTE_VALUE, Real Value
SUBSTITUTE_VALUE_2, Real Big Value
SUBSTITUTE_VALUE_HECL, Hardware Abstract
SUBSTITUTE_V, Valley Mem

I want to sort this file so the LONGEST Substitute Values are listed at the top ( so SUBSTITUTE_VALUE_HECL would be first in the list). Obviously I want to keep the related values tagging along with them, so the whole first line would be
SUBSTITUTE_VALUE_HECL, Hardware Abstract

Playing with sort This has me pretty close: sort dict.file -k1.1n,1

Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?

Aug 21, 2009

I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.

For example:

Code:

Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).

Programming :: Sorting Specific Values From An XML File

Sep 21, 2010

I need a shell script which gathers the data from a remote XML file and then displays it according to my needs.. I need this for my job due to the fact that I need to keep track price changes of euro, usd, gold, etc. The XML file I am talking about is located at this page: here. The reason I am posting the URL is that I need to use curl to get this file and it does NOT have newlines after each tag. I thought that that would be a problem. Here is what I need from the script: 1) curl to get the page 2) make use of sed, awk, etc. to display its contents in a more structured and readable manner as shown below:

A: 64.125 (% -0.26)
B: 81.130 (% -0.32)
C: 1.4930 (% 0.00)
D: 1.9590 (% 0.36)

Ubuntu :: Tweaking Nautilus' File Sorting Order?

Dec 31, 2010

I've recently switched from Windows to Ubuntu and have a question regarding tweaking the character order Nautilus uses for alphabetical sorting. In my music/graphics/etc folder hierarchies, I have used a hyphen at the start as a 'hack' to 'sticky' some folders above the rest for quicker access. This worked fine in Windows, but Nautilus ignores a hyphen in it's sorting calculations. Is there anyway, simple or complex to replicate this behaviour in Nautilus?

General :: Parsing Delimited File And Variable Scripting?

Sep 23, 2010

I did some searches and after a few hours was able to get what I needed. What I didn't find was a fully encompased means of what I'm used to in the windows world in working with delimted files. Hopefully this is helpful to others and if there is something better or leaner way, even better.We have an issue where managing printers, just viewing on RHEL w/ sys-conf-prtr we lose any number of, up to ~30 printers from lpadmin. Rather than stare and compare to find the missing ones, I wanted to make an intuitive script. This is what I came up with.

General :: Sorting In Aggregate Rather Than Tree Fashion With 'ls -Rt'?

Apr 28, 2010

The command: Code: ls -lRt Shows a recusrive listing, and sorts by modification time. But this in in tree fashion, where it first lists the contents of the current folder sorted by time, and then the contents of each child folder sorted by time. How would one accomplish this type of sort, but with an aggregate listing - all items recursively sorted together, rather than by individual folder?

General :: Sorting In Vi Editor & Copying To Clipboard

May 6, 2010

(1)There should be a command to send content to clipboard instead of 36 buffers available in vi just like ':set paste' allows pasting from clipboard inside vi using ctrl+shift+v in insert mode.(Currently I select area using mouse & right click then copy )


2)Let us say I have sentence "I am young" I want to arrange the words in this line in alphabetical order so that I get 'am I young'. First I thought replacing space by in sentence.Then !#j then type sort -n where # represents number of words.Then #J to join the filteredlines.It works but now I have file with hundreds of sentence of varying length.If I make a macro how will it know the number of words?

General :: Sorting Output By A Column With Numbers And Letters

May 22, 2011

I have a program that prints out lines like:

And I want to be able to pipe it to sort on that third column, by letter first, then number. But I keep coming getting files sorted like:

(field separations all start at same place, so columns are not jagged like above.)

I have read the sort man pages, and have tried -n for the numbers, and -k for the position to start sorting, among other things. I also tried inputting a second position to start sorting, which sort should supposedly refer to if the two entries are identical at the first place being compared, but it seems to just ignore the second one. I just can't get it to sort the numbers properly...

For now I am manually opening the file in emacs and changing them around, needless to say, very time consuming.

General :: Use The Value Of One Variable To Generate A Name For Another Variable?

Jul 25, 2010

can i use the value of one variable to generate a name for another variable? for example i want to use the counter from a "do while" loop to name and define a variable each time the loop executes. for example

objectnames1=`ls -a`
objectnames2=`ls -a`
etc.

i don't have a script yet but each time through the loop i intend to cd to a particular directory and then define a variable containing a list of each object in that directory as values. for the rest of the script to work, each variable generated has to be unique, and i can't think of a good way to accomplish this.

if using a value from one variable to name another isn't possible, can anyone think of a more elegant solution? i know limited syntax but i'm willing to read up...

General :: Why Is Reading A FILE Faster Than Reading A VARIABLE?

May 4, 2011

I don't understand the results of a simple performance test I ran using two basic scripts (running on a high end server):

perfVar.zsh :

#!/bin/zsh -f
MYVAR=`cat $1`
for i in {1..10}

[code]...

Performance test result:

> time ./perfVar.zsh BigTextFile > /dev/null
./perfVar.zsh FE > /dev/null 6.86s user 0.32s system 100% cpu 7.177 total
> time ./perfCat.zsh BigTextFile > /dev/null
./perfCat.zsh FE > /dev/null 0.01s user 0.10s system 91% cpu 0.118 total

I would have thought that accessing a VARIABLE was way faster than reading a FILE on the file system... Why this result ?Is there a way to optimize the perfCat.zsh script by reducing the number of accesses to the file system ?
