I promise I am carefully studying shell use, and much else, but right now I just need the shell instruction to search directories recursively, for files with .swo & .swp extensions, deleting the files as they're found.
View 7 RepliesI'm a frequent user of grep. I know that I can recursively search a directory using the -r flag:
Code:
// will recursively search all files
grep -r 'some string' *
However, if I want to limit my search to PHP files, the -r flag is suddenly useless:
Code:
// for some reason, this only searches the PHP files in the current dir
grep -r 'some string' *.php
Any good way to recursively search a directory and its subdirs for a string but ONLY look at PHP or HTML files (and possibly TXT files too) ? I'm really hoping for a nice, short command that doesn't involve using an exclude file and which isn't really painful to type. I do this kind of search very frequently and have resorted to either searching EVERY file which is really slow (TAR and ZIP files really slow it down) OR typing repeated commands to search *.php, */*.php, etc.
The rm command man pages discusses removing files or directories recursively. So what is meant by deleting a file or directory recursively? And what are some reasons for doing so?

I have a folder that contains my group's website. The ownership of the entire directory is set to "www-data.website" (website being a group). I want to set the sticky bit on this directory such that if anyone creates a new file, either in the main directory or subdirectories, the ownership remains like above.
Q1: I have the sticky bit set on the main directory (drwxrwsr-x). But for some reason, some of the subdirectories don't have the sticky bit set. Is there a command I can use to change the sticky bit on Directories Only (i.e., not on the files)?
Q2: Is there a sticky bit that I can set for the ownership (not group) so that it is always set to www-data?
I would like to zip only selected directories(and its child directories as well)I have many directories in the current folder like app, content, db, library etc.But I would like the zip only app and content and its child folders. I am trying the following.
zip -r ../backups/code/20110625 -i app/* -i content/* . *
But I am getting the following error. zip error: Invalid command arguments (nothing to select from)
What is the correct syntax to achieve this?
I need to strip the executable flag from all files within a certain directory and sub directories. Right now I'm doing it with a 2 step process
find /dir/ -type f -exec chmod ugo-x {} ;
find /dir/ -type d -exec chmod ugo+rx {} ;
Is it possible to modify the first line so that I can strip exec flag from all non-directory files? Since this needs to be done on a fairly regular basis across a lot of directories and files, I'd prefer not to use a bash script which would slow it down.
suppose in my current directory, I have 50 sub-directories. Now, I am interested only in about 20 of those sub-directories (whose names match a pattern). I would like to recursively list the contents of these 20 sub-directories. How do I do that ? I would like to do this in Solaris 10 and Linux(RHEL 5.x).
View 3 Replies View RelatedI have searched diligently but can't seem to find a way to search by exif date. Most of my searches turned up commands to manipulate EXIF data not just search by it. I have found some likely tools but suspect that I don't know enough bash to recursively find a .jpg file by it's exif date. For example, exiprobe and exifgrep look promising (see examples below).
I have made some progress. At first, I couldn't associate the file name with the date given but learned that the "n" option forces each output line to start with the file name. Now, I need to make the command recurse but can't seem to manage it.

I need to replace ":" from multiple files names, since I am going to copy those files from a linux partition, which admit the ":" to a FAT32 partition, which does not.
Example:

wished name: eg06_ana_21-05-06_09-21-03.JPG
I have googled a lot but I have not been able to adapt the examples given by people to my aim.
It seems that rename command is what I should use, but I have no idea to build the correct pearl expression.
I am to rename all the files within a directory (which contains multiple subdirectories) recursively without invalid characters.
I tried the coding posted above.
find . -type f -printf '%p

oldfile=$(basename "$file")
newfile=$(echo "$oldfile" | sed 's/[^A-Za-z0-9_.]/_/g')
if [ ! "$newfile" == "$oldfile" ]; then
echo mv "$file" "${file%$oldfile}$newfile"

but I get an error on both of them stating "find: bad option -printf find: [-H | -L] path-list predicate-list"

I want to copy all directories, files, and hidden files and hidden directories with one command. I want these items to replace any same items in the target directory.
I have tried several things, such as:
cp -r *
cp -aR *
but I only seem to get visible files and directories. Obviously, I am missing something. (A brain, probably....)

I've found myself in the situation where I need to create a menu in gnome/kde for a directory structure full of documents.The directory structure looks like this:
Code:
DOCS/
.. REFERENCES/
[code]...
I tried
Code:
chown -R owner:group *
which does not work on the invisible directories (why?). When I used ".*" as wildcard it changed all (visible) files including the parent directory (the one I was currently working in which is the "dot") . I can change the invisible directories owner and group using dophin but how is it done from the command line?
i am in need of linux help. iam at college and i need this back/restore script to pass this final part of an assessment. i require a backup script that will not only backup but also restore files to the relevent directories. e.g. users are instructed to store all wordprocessor files in a directory named wp. so i am needing to create a backup directory and 3 directories within that and some files within the 3 directories and then back them up ot restore them. l know i should/have to do this myself by been trying to get/understand info for the last few days and came up with zero.
View 14 Replies View RelatedI want to make a webserver with multiple users allowed to login through SFTP to a specific folder, www.Multiple users are added, lets say user1 and user2, and all of them belonging to the www-data group. The www directory has an owner www-data and a group www-data.
I have used chmod -R 775 on the www folder, but after I try to create a folder test through my SFTP server (using Filezilla) the group of the directory created has only r and x permissions, and I am not able to log in with the second user user2 and create a directory within www/test due to a lack of w permission to the group.
I also tried using chmod 2775 on www directory, but without luck. Can somebody explain to me, how can I make it so that a newly created directory inherits the root directory group permissions?
I am writing a script, in that my requirement is, if all the fill types stored in one directory from that we need to separate different different directories based on the file types.
for example in a directory(anish). 5 different types files
1- directory
2- .txt files
2- .sh files
like that and my requirement is the (1- directory is moved to one new directory(dir) which we are given in the script)and (2 .txt files are moved to another new directory(test) which we are given in the script)and ( 2 .sh files are moved to another new directory(bash) which we are given in the scrip)finally the directory anish should be empty..using bash script.how it is possible !!

View 3 Replies View RelatedI moved to Mac OS X recently and bumped into the "feature" of Mac where copying files from an external drive resets the file modification/update date/timestamp to the current date (which Windows does not), causing a disaster for my 10+ years of backup work files where date is important. So, before I learned how to avoid that (e.g. using the -p "preserve" flag in the "cp" copy command) I have in the meantime added to my new Mac hard drive many more files as well as updating existing old files.
I have a backup external hard drive with all my old data and proper modification dates. I have a Mac hard drive with reset modification file dates (a single or two particular days). The Mac hard drive has all the "true" and "current" file contents with files modified and added. I need to Copy all the original files from the external harddrive, preserving file metadata (really only modified date), but ONLY overriding the new internal Mac hard drive IF
The file contents (md5 or whatever) is the same or The file was updated after the day (which of course I can see on all files) on which the original disasterous cope was performed (implying the file is new or modified) Ensure the copy leaves all the new and modified files completely intact on the Mac internal hard drive. "No prompting/stopping of the copy of any kind (i.e., not verbose) is required but is o.k". "Recursive copy - obviously I would like to copy all* files folders and subfolders found in export".
i have a web directory that has many folders and many sub folders containing files.
i need to download everything using wget or bash.
I have a really deep directory tree on my Linux box. I would like to count all of the files in that path, including all of the subdirectories.
For instance, given this directory tree:
/home/blue
/home/red
/home/dir/green
/home/dir/yellow
/home/otherDir/
If I pass in /home, I would like for it to return 4 files. Or, bonus points if it returns 4 files, 2 directories. Basically, I want the equivalent of right-clicking a folder on Windows and selecting properties and seeing how many files/folders are contained in that folder.
How can I most easily do this? I have a solution involving a Python script I wrote, but why isn't this as easy as running ls | wc or similar?
I have a Linux machine that shares some files through NFS. The shared directory is:
/foo
I then mounted a shared directory (from a Windows machine) to:
/foo/bar
/foo/bar is mounted successfully onto the Linux machine and everything is there. However any other machine that mounts /foo from the Linux machine everything is correctly there except /foo/bar is empty. Is there anyway to do a "recursive mount" of file shares. Here is the /etc/fstab entry for the Windows share mount of /foo/bar //windows_machine/share /foo/bar cifs username=user,password=pass 0 0 And the /etc/fstab entry on the client machines that mount /foo server:/foo /foo nfs rw 0 0
I have a system where the permissions of many files are messed up. I have another system that has the same files, if I put that hard drive in, without simply overwriting the files, is there a way where I can recursively set the permissions of each file to that of this other directory?
View 1 Replies View RelatedHow can I get the last time any of the files in a directory or its subdirectories has changed?
e.g
Dir - changed 1/1/1
Sub Dir 1 - changed 2/1/1
Sub Dir 2 - changed 3/1/1
File 1 - changed 10/1/1
File 2 - change 5/1/1
The output for this for Dir should be 10/1/1 (File 1 was the last modified one). Getting the last file name to be modified is a bonus but isn't necessary.

What I would like to do is to print the contents of all text files in a particular directory, recursively. Problem being that there are directories and possibly binaries scattered around in the filesystem as well.
Trying cat * works as long as there are no directories in there, but when there are it gives an error instead and prints nothing.
I'm sure it's easy using file -f or something but I can't figure it!
How would the command for recursive search in LDAP look like when I'm searching for "cn" or "ou"?
View 3 Replies View RelatedI'm planning to writing a script to rename files recursively.
To be said that I'm using /bin/sh (not /bin/bash) as this is the only shell available on the busybox of the linux router (tomato) I'm using.
Basically I would like to rename files with extension .jpg using as a suffix the filename of another file in the very same directory with extension .avi
The reason for this is because pretty much all the DLNA devices like modern TV playing .avi files will display a thumbnail of the video when browsing the filesystem, however to do so they'll need .jpg image wit hthe same filename of the video in the very same directory.
