Trying to write a shell script called make to read a file called dirs with the following in it
programs
scripts
documents
Read file line by line and make the directories in the current directory when you type ./make dirs if no file is given then program should print usage:
make dirs filename
What is the difference between filename and ./filename? Under what circumstances is one preferred to the other?

Code:
for f in /home/user/wavfiles*; do FILE=basename $f .wav; lame $FILE; done
It doesn't work very well though. For the life of me I can't seem to discover how to use basename in a suitable way for a script like this.

How can I set a pattern that will output a filename equal to the original filename? E.g.
something.mp3 → something.ogg
And why isn't this implemented in SoundConverter?
PS: {Filename} doesn't work.
I am new to Linux, but was put in charge of our company's Amazon presence. My problem is that all of the sudden, a shell script we have been using has stopped working, and returned an odd error that I simply can't decipher. The shell script is pretty simple, and is run on our crontab (however manually running it causes the same error as well). The script name is "sendh.sh" and to run it in Linux is simply typing "sh sendh.sh". Here it is:
[Code]....
Yes, obviously those files are in the directory, I can see them through the "ls" command (or through WinSCP as well). When run one by one, each command works fine, it's just when using this "sendh.sh" shell script then it fails. Does anyone know why "" is appended to the filenames when I try to run it, or what the heck "ambiguous redirect" means?
I'm trying to use the dirs command with the +N option. The manual says: dirs [-clpv] [+n] [-n]Without options, displays the list of currently remembered directories. The default display is on a single line with directory names separated by spaces. Direc- tories are added to the list with the pushd command; the popd command removes entries from the list. +n Displays the nth entry counting from the left of the list shown by dirs when invoked without options, starting with zero.
dirs -v shows:
0 /dir1/
1 /dir2/
2 /dir3/
However, dir +n 1, dir +N 1, dir -v +n 1, dir -v +N 1 all give:

For example I have "/some/dir" which contains user's files and directories. I want to check if there are any files or directories of root. I guess I should use "find" command but what's the full command to find it out?

View 1 Replies View RelatedI am setting up a cron job, where i am calling a shell script to make few builds. I got struck at a point, need some expert inputs to proceed further. The script is categorized in 5 parts and in the last part while building software it asks for few questions like:-
1. Build mode choice
2. normal build
3. Copy Images
4. Arch
User manually has to input ans for these questions:-
1
yes
n
64
The ans's are fixed and this won't change. How shall i hard-code them or do something in the script so as when script flow reaches to this point it automatically take's these value. So far the cron job is not getting completed as it's waiting for user to key in these values manually. I had faced similar issue while building kernel modules but there it was easier as i had to take default values always:-
Consider that I am building my application in Linux shell using make command but somehow the build fails. Is there any way I can find out that the build has failed (of course looking at shell for error messages will do the job for me but I don't want that). Is there any flag make or shell will set/reset if such failure occurs ?

I want to gave much details as possible. working directory (~/a1/shell) in the shell directory i have Makefile. also in the shell directory i have subdirectory's (obj, src, include)
My current Makefile

I wanted it so: all .o files are created in the obj subdirectory, and my application, sshell, is created in the shell directory.
I am getting this error when i run the make run: No rule to make target 'shell.h', needed by 'shutil.o'. stop

I have some school work that involves creating a script that creates a backup of my /home folder, everything goes well but the problem is with the filename.
I am supposed to create a .tgz with the filename : hostname-day-date-HH:MM:ss.tgz
The .tgz gets created with the correct filename but when I try to unpack it the filename can't be resolved, it's the : that mess things up.
in directory a_dir, have a file named a_file.i can type "source a_file" under directory a_dir and execute successfully.but if i write the command to a Makefile under directory b_dir, the "source" function can't be executed well. it will generate some error message like this:
./a_file: line 1: setenv: command not found

I have to extract last number from filename.
ex- my file name is a10b8c1000

but sed looks for content inside file.
I would like to remove a part from wiz_khalifa-black_&_yellow-(82_bpm).mp3

I'm trying to use tar which I've used a bit before but have never had to do this so I'm unsure. I'm trying to remove parent dirs from the backup. example;
Code: tar cvpjf /path/to/backup.tar.bz2 /path/to/the/source I want the backup.tar.bz2 to only contain the contents of source. At the moment the contents of the backup.tar.bz2 have the following file structure /path/to/the/source/files. How can I remove the parent dirs from the backup.tar.bz2? Alternatively, How could I just extract the contents of source with out the above folder structure? at the moment when I extract the backup.tar.bz2, I get the full folder structure in the location that I extracted it to.
I need to list a directory recursively but I want to skip subdirs that were already mounted. There are 2 cases:
a) a filesystem was mounted twice, like in this example:
- "/dev/sda2" was mounted on "/mnt/mnt_point1"
- "/dev/sda2" was mounted on "/mnt/mnt_point2"
I want to list "/mnt" but descend only in "/mnt/mnt_point1"
b) part of the file hierarchy was remounted somewhere else, with "mount --bind":
- "mount --bind /home/user/tmp/test /home/user/tmp/mounted_test"
I want to list "/home/user/tmp" but descend only in "test" "statfs" and "statvfs" don't offer any information to discern if a dir was mounted twice. One solution would be to read "/etc/mtab" (as "find" command does it) and perform some checks, but I think that this is pretty expensive (one has to read /etc/mtab every time one encounters a dir; if this file is read only when program starts, a mount could occur in between reads, so that the program will be inaccurate). Another solution would be to filter kernel events (via libudev or Netlink) and do this reading of /etc/mtab only when a MOUNT event was issued.
Is there a way for me to rsync two directories comparing only filenames (and not file size, date modified, or any other criteria)?
View 2 Replies View RelatedI have a directory that has a large number of files, around 1.5 million at this point. If I go to the directory and type in "ls filename" for a filename that I know exists, ls just hangs. I have let it run for over 20 minutes and it never does anything. Up until yesterday the directory was working fine through samba serving up files, but now it doesn't return anything. How to proceed from here?
