Programming :: How To Write Script That Would Use Join Across All Files In Directory?
Aug 19, 2010
I have a bunch of files that contain a date, then data. When I use join, I get exactly the output I need. But manually joining the first with the second, then that output with the third and so on would take days. I have thousands of files. Can any of you folks help me write a script that would do this?To put it another way, for clarity's sake, here is what I am currently doing
If I were to repeat that 3000 times the final output would be what I need. I know a simple script would do this for me, but I can't figure out how to write it.

How can I write a script that will go through the files in a directory and print on the screen the name of the files stating if it is a file or directory. The directory is already provided by the user.

I'm using OpenSSH 5.5p1 on Fedora 15. I'm trying to get a chrootDirectory to work. Specifically trying to figure out why I can't write files to a sub-directory of the chroot directory. I created a user test_user and created a group called sftp. I added test_user to the sftp group. I edited /etc/ssh/sshd_config as follows:
Code:
Subsystem sftp internal-sftp
Match group sftp
ChrootDirectory /home/sftp_users/%u
X11Forwarding no

I'm trying to write a script that will calculate a directory size and if the size is greater than 4GB, it will send out an email. But I am getting the "integer operation expected" error when it tries to calculate the current disk size. Here's my script.

SUBJ="Ready for DVD burning on `hostname`"
MAIL="/bin/mail"

I'm trying to write a bash script that gets the list of files in a directory and puts them into a variable, then checks each entry and outputs them as follows:
item1 is a FILE
item2 is a DIR
item3 is a DIR
etc etc.
I am able to get the list of files into a variable, but unsure how to get the output I want.

In my tmp directory some logs are creating continue (with name logs.txt1, logs.txt2 up to 245). Some times these logs are creating continue within 1 or 3 second gap, now I want to write a bash script that continue monitor the tmp directory and if any time logs create simultaneously within 1 or 3 section gap it will alert me..( generally logs are create with the gap of 5 or 10 minutes duration or some time after one hours )

I'm trying to write a bash script which will find files then move them to a specific directory.
So far I have:
Code:
#!/bin/bash
#script to find and move files
src_dir="/path/to/source/directory"
des_dir_mov="/path/to/destination/directory/for/movies"
des_dir_img="/path/to/destination/directory/for/images"
find $src_dir -iname '*.avi' -type f -exec mv '{}' $des_dir_mov ';'
I'd like to have all the possible movie file types then the image file types checked in a loop.
Every time I try to include an array in this script it breaks

Here is my /etc/samba/smb.conf file:

I have a folder of 2 many files that the old ls just hangs.
I am trying to write some log files such as;
I don't mind doing one at a time, but I am just playing and even getting the listing I am not getting the date stamp, I have the following;
That does create the file, but all the files look like this;
So basically it's just sticking that ls inside the log file and not actually running the ls, so how can I use the above type to get files just created per year?

I am trying to write a script to edit text files formatted like this:
Code:
(MCAL@Contig766:0.30207,CGIG@CVIR_Contig1014:0.13977,(HASI@HDIS_Contig573:0.16828,(CAPI@LCIN_5594371:0.36581,CFOR@FQH745302RIQ7Y:1.91244)0.160:0.00019)0.939:0.15648);
There are never line breaks or spaces in the actual files.
I want to delete all instances of the character "@" and everything between it and the next "," (including that comma) or the next ")" (including that close parentheses) whichever comes first. My desired output file would be like this:
Code:
(MCAL,CGIG,(HASI,(CAPI,CFOR)0.160:0.00019)0.939:0.15648);
I figured out how to do this using sed for either "," or ")" but both looking for whichever comes first.

I am trying to understand the join command. I wish to join two files:
Code:
$ cat test1
a 0
b 2.51
c 19.85
$ cat test2
a 0
b 2.51
[Code]...
this is great but I do not understand why join ignores the -e flag and fails to insert FOO in the empty field.

I've got a collection of comics on my computer which consist of single images in .jpg. I am trying to join them all to a big .pdf, so that I end up with one e-book per comic instead of a bunch of single images. I already tried importing it to Open Office, but that way I will have to rescale every single image to fit a page, which would take ages.

find . -type f -name "*" -print0 | xargs -0 --replace=% mv % `pwd`
works fine at moving all files anywhere below the current directory to the current directory.
My question is can it be modified so it only moves all the files up one directory layer? Otherwise I shall have to cd 100 or so times and run it in each directory i want to compress...
I imagine the directory below which the file is stored is in the % somewhere it is just a case of extracting it and applying it to the mv command, yes?

I once had a script that when run would find the first 800GB of files in a directory (including subdirectories) and write them to a file (ie: ./800gb.sh > manifest.txt).I used this to create manifests of 800GB worth of data from large directories in order to dump to tape (LTO4).I'm sure its gotta be a pretty simple script, but I am not very skilled at writing bash scripts.
