View 4 Replies View RelatedI made a fresh ubuntu server installation with two of the same hard disk drives in RAID1 mode.When the installation finished, I had some errors in random times rendering the system unresponsibleCode:end_request: I/O error, dev sda, sector <Number>From the above error, it looks like there was a problem with disk sda so I decided to change it with another same disk and rebuild the RAID1.
When I put the new hard disk on it, created a raid partition of the maximum allowed size and tried to add it to the raid array (after having removed the previous disk) I got an error saying that the new partition is not large enough to join this existing RAID1 array!Then an "fdisk -l" command shown something weird...The existing working hard disk in the RAID shows that it has 38913 cylinders but the partition starts at 1 and ends at 38913+1=38914!!How is this possible? When I create a partition myself I am not allowed to put numbers larger than the total number of cylinders!
Code:
# fdisk -l

I need to write shell script which can take number of files and count total rows from all CSVs and display total number of rows counted in all files. Is there any possibility of doing that using shell script and if yes then how.
View 4 Replies View RelatedI have a file with a random word on each line (3k+ lines). How can I get the lines with only five characters? I tried using grep file | more, but it returns all the words (even those less than 5 characters).
Edit: I also tried grep '.{5}' file | more but it doesn't show anything. And grep '.{5}' file | more returns all lines with four or more characters (I'm really confused about why it's doing this).
I would like to modify the content of a text file in Linux, in the following way:=> the file has several of these lines:./run_pest3 ./g134366.04080_0.062 x 2_d043 1 0.43 results_EC=> I want to modify all lines to be:./run_pest3 ./g134366.04080_0.062 x 2_d043 1 0.43 results_EC0.062i.e., the last number of $2 should be "attached" to the end of $7, for each line.

type=strongsubj len=1 word=absolve pos=verb stemmed=y priorpolarity=positive
type=strongsubj len=1 word=unique pos=adj stemmed=n priorpolarity=neutral
type=strongsubj len=1 word=absolutely pos=adj stemmed=n priorpolarity=neutral

type=strongsubj len=1 word=purecolor pos=anypos stemmed=n priorpolarity=negative
type=strongsubj len=1 word=accusingly pos=anypos stemmed=n priorpolarity=negative
I want to add the plural for the noun, for example if find this line:
type=weaksubj len=1 word=friend pos=noun stemmed=n priorpolarity=positive
will add one more line :
type=weaksubj len=1 word=friends pos=noun stemmed=n priorpolarity=positive
where we add "s" for the word friend
I did try to do like that:
<code>
cat file | while read LINE ; do
set -- ${line}
if [[ "${4#pos1=}" == "noun" ]];then
#I tried this line but it doesn't work properly:
v3==$(echo $line |sed 's/$3/$s') #I want to find the third word "word=friend" in that line and add "s" after that word
# I don't know what command to add this new line "$v3" to the file ???
done
</code>
I am using 'sed -e /foo/d' to match lines which I want to delete from a file. I discovered I have some lines which contain random (extended?) characters like 'ủ' which I would also like to delete. The lines in the file should only contain alpha numeric characters.

affected: mousepad and tcl/tk applications
I am using mousepad and tcl/tk application to view text files with long lines. Sometimes ago I found that some characters (part of line) in long lines disappear. The problem is shown on a very small video. [URL]
# echo "foobar" > /tmp/word
# cat /tmp/word | wc -m
7
I want to print the number of characters in the file. Why does it output 7? Am I missing something obvious?
manpage:
-m, --chars
print the character counts
In Windows's CMD when you execute a command and then start writing the next one (while still executing the former one) the characters remain in the buffer and they all come up nicely to the new line once the previous command has been executed. In Ubuntu when I do this the newly typed characters annoyingly get in the beginning of the previous command's output lines. I don't really understand why isn't the default method as in Windows's CMD. I mean otherwise almost _everything_ sucks with it when compared to Unix/Linux shells/terminals (commands are longer, syntax is annoying, etc.) So I'd like to know how to do this in both Bash and Zsh.

I'm attempting to search through a rather large assortment of html files created in Word using 'save as html'. what I'm trying to do is find and delete these tags (they're causing browsers to display black diamonds with white question marks):
<span style='mso-spacerun:yes'> </span> Tags contain from 1 to 4 spaces between opening and closing. I get positive results from this:
grep <span style='mso-spacerun:yes'> filename.html but once I attempt to tell it to match any number of characters up until the next '>' symbol, it tells me I'm using an invalid regex: grep <span style='mso-spacerun:yes'>[^>]+> filename.html
I've been nose-deep in regex tutorials for the past day or so, and I'm still not understanding why this doesn't work. If I put the pattern (without backslashes) into a separate file and use `grep -f patternfile filename.html`, I get no error but no matches either. So far as I can figure, the above regex boils down to:
Match the string "<span style='mso-spacerun:yes'>", followed by any number of characters that are not a ">", followed by a ">". If someone could tell me where I'm going wrong with this,

I'm looking for a way to insert the number of lines in a file to the start of the aformentioned file. This should be simple but as I am not used to scripts in Linux, I am finding it tough going. I can find the number of lines in a file easily enough via
filesize=$(awk 'END {print NR}' $1)
but as for inserting this into the first line, i'm failing to do so. I've tried some of the other approaches on these forums but none so far have been able to do so.
I've tried:
sed '1i$filesize' $1
but sed i requires a string, not a variable so no go I've also tried:
mv "$1" "${1}.bak" 2>/dev/null || touch "${1}.bak"
cat $filesize "${1}.bak" >"$1"
but again with no luck as cat seems to need an input stream Just to recap, i want to insert a line at the start of a given file that holds the number of lines the original file has.
ie the file:
a
b
c
d
e
should become:

I quit using Fedora when FC4 came out, but I decided to switch back now that F11 has come out. I'm liking everything so far, though it is different from what I became used to (Ubuntu). My main question so far has to do with language support, and I cannot seem to find an answer anywhere for this. I need to have language support for several languages (including support to enter complex characters) for all applications for which it they are available. How do I install all the language files at once for, say, Korean, rather than installing each library one by one?
View 6 Replies View RelatedDownloaded the F10 live CD. Booted to it, got past the white, blue, and dark blue loading bar then my screen would be covered in black and white lines. No sign of the GUI except for a mouse cursor. ctrl+alt+backspace would cause the display to blink off and then come back on to the same thing. ctrl+alt+f2 would bring me to a terminal, logged in as root, but from there I couldn't do anything. startx would tell me I had x running on another screen.
hitting tab when booting the livecd and adding "xdriver=vesa" and "nomodeset" to the boot line. That works. I get to the desktop at native res with desktop effects. Killer. I tried to install; install went flawless, rebooted to my HDD and the same issue, black and white bars. When booted to my HDD, however, ctrl+alt+f2 doesn't bring me to a terminal, it causes my monitor to go into sleep mode and my computer becomes unresponsive so I can't do anything from the command line.
Here's what I'm getting at : how do I get my installed version of F10 to do the "xdriver=vesa" and "nomodeset" args that the livecd can do?

installed fedora with the minimum option on the dvd. After that i logged it and im tring to install gnome, heres the catch though i only have 950MB worth of space. I noticed if i use the groupinstall "X Window System" it fails because of the space. Also it installs alot of things that I am not interested. what are the command lines to install gnome but with the minimal, no FF, no evolution, you get my point.
