I want to read values from a file...these are basically one word values, that is to say that the text file I want to read from contains lines of word length 1, as in:
word1
word2
word3
[code]...
I am splitting a file based on the values read from an input file. The below one is the script.
1)How do I add the header which is present in the original file to the new split files created?(For eg. pharmacyf conatins header as table column names. The new files created (ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat) are without the header).
2) Also the script is creating 0 byte files for the pharmacyids which are not available in the intial file? Can this be avoided?
for pharmacyf in *
do
tablename=`echo $pharmacyf |cut -f4 -d'.' `
while read pharmacyid
do
grep -w $pharmacyid $pharmacyf >> $OUT/ODS.POS.$pharmacyid.$tablename.$CURRENT_DATE.dat
done< inputfile
done
I am trying to torrent using transmission. The problem is, when I click a link to download something, I just get
"/tmp/mn3BZo4y.torrent.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator."
This is happening on all torrent sites.It never comes up with an "open with" option or anything.
how easy it would be to read the contents of a physical disk that was part of a larger logical volume. The disk contains a "Linux LVM" partition that spans its entire size. My problem is that one of my disks died, and I have to send it back for a warranty replacement. However, the disk is dead, and I can't zero it out. I'm just trying to assess how difficult it would be (or at least how likely it would be) for a tech that's checking out the disk to get at the data.

I have a fallowing simple bash script:
Code:
#!/bin/bash
echo -n "Please insert your name: "
read NAME
[Code]....
It works fine, but is it possible to have default values using bash read(1b)? I mean if user is prompter for sex, he just pushes ENTER and by default 'm' is chosen. Or if user is prompted for hometown and he doesn't insert anything, but just pushes ENTER button, 'New-York' sis chosen by default Are such default values possible in bash?
I have an assignment where I have to use an expr command to read values from File1.txt and File2.txtHeres the assignment:Create two files.File1 has one line with the value of 5.ile2 has one line with the value of 100.Edit your new file using Gedit or VI and change it so it performs the following actions:Read the values from the files above (file1 and file2)Divide the value from file2 by the value in file1.utput the result of this calculation to a new file called file3. My .scr file is week3prog3_george, in file1 I put var1=5, file2 is var1=20.Then, I put in my .scr file this:
#!/bin/bash
expr File2.txt / File1.txt
It returns an error message stating "non-integer argument."And...how do you point the .scr file to read values from two different files, and the book my school has provided does not contain the info I need.
I'm doing some bash-scripting and want to be able to print some text (just plain text) files into the new bash-scripts, created within a loop. Here's a short example of what I do:
Code:
# main bash script #
#!/bin/bash
##Filename
variable1=10
for ((j=0;j<=40;j+=1))
do
## Create another bash-script
echo "#!/bin/bash" >> bash_script_$j
... some stuff...
cat file1.txt >> bash_script_$j
... some more stuff...
done
where the text file (file1.txt) I want to print in the the new bash script looks something like:
Code:
# file1.txt #
...some stuff...
logsave log some_program($variable1)
mv output_$j folder_$j/
... some more stuff...
I.e, the text file contains variables such as "$j", "$variable1" etc that are undefined. Doing the above works for creating new bash scripts (bash_script_1 - bash_script_40) but the variables are not determined. I would like, if possible, to somehow print the text in file1.txt into the new bash-scripts with the variables determined, i.e:
Code:
# bash_script_1 #
...some stuff...
logsave log some_program(10)
mv output_1 folder_1/
... some more stuff...
The text files I read are quite extensive so I would really prefer not having to paste them into the FOR-loop directly.
I would like to grep all values other than encrypted password from /etc/shadow fileFor example,each line consists of 8 fields separated with :/The only thing that I want not to print out is the contents between first : and second : (encrypted password)

I have to read a couple of numbers from a random.txt file. In this .txt file there are random numbers. They are separated by a space. Example if you opened test.txt:
test.txt :1 6 1 3 6 8 10 2 4

I need a webserver (LAMP) running inside a virtual machine (#1) running as a service (#2) in headless mode (#3) with part or the whole file system encrypted (#4).The virtual machine will be started with no user intervention and provide access to a web application for users in the host machine. Points #1,#2 and #3 are checked and proved to be working fine with Sun VirtualBox, so my question is for #4:Can I encrypt all of the file system and still access the webserver (using a browser) or will GRUB ask me for a password?If encrypting all of the file system is not an option, can I encrypt only /home and /var/www? Will Apache/PHP be able to use files in /home or /var/www without asking for a password or mounting these partitions manually?

View 3 Replies View RelatedI have a .txt-file with ~50.000 lines of numbers, generated by a mathematics program. From this file, I need line ~ 1.100 to line ~16.000 (these lines are always the same btw, this may make the solution easier, dunno) to be copy/pasted to another file, where the lines ~500 to ~15.000 (also, every time the same) should be overwritten by the aforementioned lines...I haven't found or come up with anything that works yet, mostly I find solutions to copy everything from one file to another but I can't find something to specifically overwrite a part of a file with part of another.

View 4 Replies View Relatedso what i did first was obviously use wubi to download and install ubuntu. after a 14 minute download, i was finally ready to proceed with the installation. i was excited, however, little did i know the installation would soon be a complete train wreck with little children aboard.here i am, sitting down, rebooting my LAPTOP computer (Acer Aspire 5336, Intel(R) Celeron(R) CPU - 900 @ 2.20 GHz 2.19 GHz, 3.00GB RAM, 64-bit operating system -- bought it at walmart because my desktop is still at my parent's house),and then i choose to boot up ubuntu instead of windows 7. everything looks like it goes fine so far.
there were a few errors but it went by so fast i could only read the "error" part. i wait for the installation thingy to show, but it doesn't! the screen goes completely blank after a few more words show up and disappear all in a blink of an eye, so i wait a very long time. it shows a purple screen, and asks me to choose a boot thing or w/e. i choose linux (there were other options like windows 7, linux recovery, i forgot the rest), then it just restarts the computer and i choose ubuntu and it does it again, however it never shows the purple screen!
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)
