I have been messing with diff and grep for 2 days now without result
I am trying to match a file consisting of words to many separate other wordfiles in a specific directory. one by one.
What i want the script to do is to report how many matching words my main file has with every file in the directory, each in turn
setup:
Each of em are plain text files with 1 word per line
Output should be something like:
SCRIPT REPORT:
In a bash shell script, I want to do something like this:
Code:
if [[ $(ls -ld /some/dir/foo_* | wc -l) -gt 4 ]]; then
rm -rf first_match_of /some/dir/foo_*
[code]....
I have many files in a folder for example
Kiran.txt
Kiran1.txt
Kiran221.txt
Kiran144.txt
Time.csv
[Code]...
From this directory, I want to know how I could use grep to display files based on part of their filename - for example those starting with "Account" or those ending in ".sh".
Im constructing a menu for a program using case. I have all my normal input options mapped out but i want to have a * ) option so that if something else is inputed, it displays "Incorrect input" and then resumes the normal menu function. How do I do this? Ideally, I'd like it to display "Incorrect Input" and then accept more input for the menu.

I have a very simple bash script:echo -n Create home directory?:
read HOMEDIR
if [ $homedir="y" ] || [ $homedir="yes" ]; then
homeval=" --makehomedir"
[code]...
In a bash-script, only the case if a regular expression does not match is relevant.herefore I used the exclamation mark !. But where to place it?
These two work fine, but are they equivalent?
Code: if ! [[ $abc =~ $pattern ]]; then or
Code: if [[ ! $abc =~ $pattern ]]; then Where is the ! placed more correct?
I have a file with joker character patterns:
./include/*
./src/*
etc.
From the current directory I would like to recursively get the list of files that do not match these patterns.
I've a string "this.is.a.name", and I would like to return "is.a.name". How can I do that in bash?

I have two table files with x (1st column) ,y (2nd column) coordinates and intensity (3rd column). I need to match these two tables and divide the intensities at the consecutive coordinates on the 3rd column. The problem is the size of the tables are not same and I want to ignore the lines if they are not in one of the other file.
Here is Table 1:
Code:
-7.500-30.00013.006
-7.500-22.50037.952
-7.500-15.00060.962
-7.500-7.50040.922
-7.5000.00014.348
code....
Here's the bash script:
Code:
FILES="/usr/sbin/accept
/usr/sbin/pwck
/usr/sbin/chroot
/usr/bin/fakefile
[code]....
Notice the extra" file size" lines in there? What's causing that? I'm trying to learn more bash skills. I have no experience with awk because I have been unable to understand it's basic necessity. But I thought maybe if I try it with some test scripts I might become more interested in using it more and expand my very limited capabilities.
how I can use the mv command to move a file that matches *.ext regardless of the case?
I would like to be able to move:
*.ext
*.EXT
*.ExT
....and so on with a single command. I do not want to have to type out all combinations of this single file extension in my script because my file system is case sensitive.
I'm using Ubuntu for about a half year. Currently version 10.10. The next problem I have with Nautilus: He have it in ListView. If I want to rename a file then the entire file is selected and not only the first part. So the file extension is also selected. I think this is a bug, whoich can be found on the Internet, but I do not find a solution. Does anyone here have a solution?

1.png
1_thumb.png
1-1.png
1-1_thumb.png
[code]....
I want to list all the files that don't have a copy with the same filename with -1 somewhere in it. So, in the example above, the results would be 3.png.
NB: the file and its copy with "-1" in it will be the same filesize, if that helps.
Quote:Originally Posted by topcatI would like to know how i can write a shell script to delete a line if a particular pattern exists?E.g. I have a text file with multiple lines. Say 1000s. in the following pattern.
username@email.com:149.0.3.4:1
username1@email.com:149.0.3.4:1
username1@email.net:149.0.3.4:1
username1@email.edu:149.0.3.4:1
If the patternusername@email.com exists then the line "username@email.com:149.0.3.4:1 should be deleted from the file.I have a very similar question but I need to delete one line in a file which matches one very precise instance of a string only. Let's assume I have a file composed of thousands of lines and let's call the file chap-secrets. Let's take the following sample entries:
Code:
#USERNAME SERVER PASSWORD IP
pp pptpd blahblah *

I 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.

For example, myname@mydomain.net has myname as the local part and mydomain.net as the domain part.I get the whole email address with %s. I want to speed up the lookups by writing better database queries.I've had no luck finding this in the otherwise well documented postfix.
View 2 Replies View RelatedI know that the question could sound weird but...I was wondering if is possible to download one or more parts of a file.
For example, the first 10 mb, or the latter ones.
I know that there are some apps that let you do segmented downloads, but, is there anyone that let you choose the segment to be downloaded? If not, can this be accomplished with any linux command-line application?
we have access to one domain name , 1 internet ip address and may servers hosting different part of site. I want them all to be accessed via same web site . some of the server in our network are embedded devices.they have their specific utility being hosted on that machine. So the severs are bound to be distributed . I just wanted to know how can I access them via single ip, domain name.

However after all the downloading is over, an error occurs when I try to extract the .gz file. Is there any way I can download only the missing part of the file?

View 4 Replies View RelatedWhen I look in /var/cache/apt/archives/, I see packages I recognize that I downloaded. But, I also see packages that I know I did not download, but rather were part of the initial installation of the image iso file on the CD. For example, the package for Abiword is in there. I would like to know which packages in this directory I installed, and which were part of the initial installation.
How do I know which packages are part of the installation from the image iso file on the CD? Once I know that, I would make a copy of all the other packages in this folder onto a DVD, so if I ever need to reinstall Ubuntu 9.10 I will know which packages to install over and above those part of the initial installation off the iso CD.
lets say there is one very big file on some server and i just want to download first 1MB. How can I do it on Linux ?
