View 5 RepliesI 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.

I have a lot of filenames (strings) following the same convention
m02_+1+7_London_0000$01.cfg
m02_+1+8_London_0000$01.cfg
m02_+1+8_London_0000$01.cfg
[code].....
What I want to do is to create a script that will interpret the following string and save into variables part of its name
m02_+1+7_London_0000$01.cfg as
------X-Y--City---------
X=1
Y=7
City=London
[code]....
then I want to copy the files that go all the files with the same City and X and Y to the same subfolder City/MX.Y I will need some help start doing that. And I think the first would be to get part of the filenames strings into variables.
I have to copy some log files with a cron job; I'd like to copy only the newer files added because I run the script with a weekly cron. all the log files are named like "10-03-29.CVS" and reside in a dir. When I copy I'd like to copy only the files not already copied with the last cron job.

View 16 Replies View RelatedI need a script to copy music from a network drive to my local disk. I require the script to auto mount the remote server, then to create the directory path to the mp3's I have a list of all teh songs in the following format, note some have spaces.
\7800SPARE4UsersPublicMusicSample MusicKalimba.mp3 \7800SPARE4UsersPublicMusicSample MusicMaid with the Flaxen Hair.mp \7800SPARE5UsersPublicMusicSample Song Sleep Away.mp3
I can use the following to mount the directory:
mount -t cifs //7800SPARE4/Users /dest-o username=user,password=pass
I'm thinking the best way would be to get the share name 7800SPARE and the grep for all these in the list, then mount it and do a while read LINE However I would need to creat the folders, I am unsure on how to do this. I think I would need to sed the backslashes to forward ones and then use rsync? Then unmount and move on to the next ones, if I can't mount the share It would be nice to log it and skip it.
I'm facing difficulty while writing to an already existing file . I'm making a shell (programming in C). I want a file (say , logfile) to keep a record of all the commands a user enters. For the first command it runs fine , but for the second time and thereafter it overwrites the previous contents. How do I avoid this?
View 3 Replies View RelatedI have a configuration file I put ndd commands into for servers settings and I'm running into and issue where they are only off by one character so I keep overwriting the setting.
The file has these two lines in it:
As you can see the only difference is the q0 on the one entry. With the code below I just keep changing/adding a line to the file and not just finding and fixing the each line. I cannot seem to find the right "terminator" for an exact match. I do understand why it's doing it, I just don't know what to do to fix it. What am I missing?
In the end I just want to search this file and make sure these two lines are in there and set properly.
I have a directory where there are folders and in them some .txt data files. I am trying to output a .txt file with the folder name and the number of .txt files in it using gawk. However, when I run my shell program, because print is nested in a "while" loop, gawk overwrites what's already saved in the output file. I want gawk to print "new" output in a new line without overwriting the already existing text in the output fil
#! /bin/sh
# getting the folder list and the number of folders
ls | gawk '{print}' > ../folder_list.txt

I would like to know how do I print the line # in a script. My requirement is, I have a script which is about ~5000 lines long. If there are any errors happen I just exit. And I would like to add the line # of the script where the error happened.

#!/bin/bash
trap "echo 'you got me'" SIGINT SIGTERM # to trap ctrl+c
echo "Press ctrl+c during 5 sec loop"
for ((i=0;i<5;i++)); do

How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!

I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?

View 5 Replies View RelatedI would like to get the filename (without extension) and the extension separately. The best solution I found so far is:
Let FILE="thefilenameofsomefilesfor_instance.txt"
Code:
NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.

I'm writing a bash script to copy a list of files and do some stuff to them. Basically, I have the code written that does what it needs to do, but I can't quite understand why it works. I was hoping someone could clear up my understanding a bit.
Code:
The first line generates a list of files. I wrap each line in quotes because they usually have spaces in the directory names.
The second line changes IFS, and I understand what IFS itself does. What I don't quite get is what the separator becomes with that echo statement. If I'm reading that correctly, the backspace will remove the newline and essentially the result is nothing? I found this solution on a web page somewhere, but it was years old and there was no real explanation.
Ubuntu :: save copy of bash entries / history?
View 7 Replies View RelatedI know how to redirect the output of a terminal to a file. For example, if I want to list all the files in ~/Documents and output to a file called test.txt, I would do this: ls ~/Documents > test.txt The question is, can I copy the output to test.txt AFTER I have carried out the command? This would mean that I wouldn't have to know in advance whether I want to copy the output to file. I want to do something like this: ls ~/Documents Then this: <bash command for copying standard output to test.txt>
View 2 Replies View RelatedLets say I log in to bash, open a file in vi, then using alt-f2 I open a new terminal. After logging in I navigate to a second file and open that in vi. How can I CnP between these two files?
I found this from [URL]. I'm not familiar with this command shift-8-y-y. I follow the vimtutor and use virtual mode. I tried this sequence and was unsuccessful.
And, I read this about registers. I found a mention of using double_quote-p to 'put' or paste the register, but this does not work in a different file. The second file reported the register empty.
Alternatively, I read in the VIM docs, it is possible to open multiple files under split screens. This may be a course to a solution. The need I often encounter has me navigating in a different bash window to find a file, then wishing to copy between the two. Whereas, I imagine, a split VIM window useful for files in the same directory.
Is it possible to use the keyboard in order to select some text in the terminal windows that is not in the currently edited line? (for example, in order to copy part of previous command output).

View 3 Replies View RelatedI want to create an alias or shell script (I use bash and ksh at work) that will work like mv -bf but instead of adding a ~ I want to add a date time stamp. So if I move a file like greg.txt into a directory that already has a greg.txt it will rename or copy it to greg.txt.date-time. I want this to be pretty global, seemless, and *automatic*. I am familiar with 'no clobber' and it doesn't meet the requirements.

how do you copy an entire line and add that copy at the end of the same line?
For example, sometimes I rename a collection of files with a command like:

I am experiencing a bug when overwriting files on FTP servers using the default nautilus FTP client.When I upload a file to replace an existing file via FTP, after I confirm the prompt asking me to overwrite, the content of the newly uploaded file is appended to the existing file's contents. The resulting file contains the content from both files. In order to fix this bug, I am forced to delete the existing file before uploading the new file.If I upload the same file multiple times, the error will continue to occur and append the new file to the existing file.
