General :: Search & Replace Back Slashes To Forward Slashes In Windows

Feb 11, 2011

Lately I've been needing to delete new untracked files from my versioning system. Being in linux I use: hg status -un|xargs rm And it works nice, but when doing it in windows, hg status lists paths with backslash so that is where stuff goes wrong. So then I try: hg status -un|sed 's/\///g' ...but I get the error: sed: -e expression #1, char 8: unterminated `s' command

Then I try some ascii: `hg status -un|sed 's/o134/o57/g'`...that gets me: sed: -e expression #1, char 14: Trailing backslash And some scripting: hg status -un|sed 's/`echo `/`echo /`/g' ...that gets me: sed: -e expression #1, char 19: unknown option to `s'

I try all the last with any other characters and I get the expected output... so I'm completely lost. I have cygwin, of course, and I want to avoid using a file (that is what I've been doing).

Ubuntu Security :: Understanding Unix Style Permissions

Jul 20, 2010

On Windows, you can go to a file's permissions and it's clearly stated who can do what. You can choose between individual users or groups such as 'everyone' or certain types of users such as 'domain users'. You could create a clear cut list of every single user/group on the system and what their permissions for a file are and have it neatly displayed in a list.On Unix, we have octal permissions and sticky bits. I understand the whole concept of rwxrwxrwx (777). The first three are what the file owner can do, the second is what the main group the user belongs to can do, and the third is what other users can do.

But, when you view a file's permissions you are only getting the permissions as they apply to the user that owns the file. For example, as I understand it, if I viewed a file that only the root user had rwx permissions on and everyone else could only read. The permissions would show up as rwxr--r-- (744). But, those same permissions would show up to any user as 744 as well. Since the last 3 characters are what applies to "other users" (pretty vague). How would someone know what users in particular those permissions apply to? There could be one "other user" that can rwx that file and another "other user" that can't.Also, why just stop with the main group? What about other groups? A the user Foo's main group he belongs to might be Foo. But he could also belong to the groups Boo and Zoo, which belong to other users and would give him full rwx permissions over Boo and Zoo's files just as if he were Boo or Zoo.

Then you have the whole sticky bit thing that makes it so that files can be owned by the same person and at the same time be made use of (to varying degrees) by other users. To chmod the UID you'd chmod 2777 or for GID 4777 (just an an example). I did this for a file and it allowed a standard user account who was previously unable to run the command to be able to run it. But, how can that work when I didn't anywhere specify what particular user (or groups of users) that sticky bit applies to?

I'm confused about this whole thing to the point that I'm not even sure exactly what questions I should be asking or even if my examples are even 100% correct. I just sort of ranted about some specific things that floated to the top of my head. Permissions are easy to understand when your running a Unix-like system on a single user desktop. Because the only users/groups you have are root, the single user, and various system users/groups that you don't really need to worry about. So a file with rwxr--r-- means that only the Root user (not even members of his group) can edit the file and you can't unless you use sudo. Because the "other user" in the last 3 characters always just means you. But, things seem to get a whole lot more complicated when you start adding in multiple users. Can someone explain this or link to a "for dummies" article that can explain all of this to me in a way that someone who's used to Windows style permissions can make a connection between the two OS families and their way of handling these things?

General :: Install Package To Convert One Unix Book Into Pdf?

Dec 15, 2010

I wanted to install this package to convert one Unix book into pdf. Since I have not set up the internet in the debian, I download the .deb files in winxp and transfer these files to my pen drive and then access it in the Debian. So I got all the 'depends' packages for the chm2pdf from the Debian Packages site and tried to install. Console was still asking for more dependencies. If I have got all the 'depends' packages which are required for chm2pdf, then why does it give problems ?

Programming :: Replacing "slashes" With Back Slashes - Escape Character ?

Jan 7, 2011

Usually if I have to replace a character in a string I used the sed /s/ command. However, I am having some difficulty in doing the same thing when I have the following string in a variable in my shell script and I need to replace all the forward slashes ("/") to backslashes ("").

For example, this is what I am doing:


Not sure how to escape the slashes in this case.

General :: Windows Command Prompt Auto-completion With Forward Slashes?

Jul 26, 2011

I switch between Linux and Windows quite a lot and it's annoying the hell out of me that the Windows command prompt won't auto-complete directory paths when I press Tab if I use forward slashes like in Linux.For example, if I'm trying to navigate to a directory 'bin':

cd /path/to/dir/b <tab> - this won't auto-complete to 'bin'
cd path odir <tab> - this will auto-complete.

Can I tell the Command Prompt to use forward slashes instead?

General :: Awk: Awking The Right Separator With Slashes - Colons - Commas (date Time And Data)

Jan 4, 2011

I wrote a hack script that outputs the following every so often: Code: 01/04/11 10:33:02: 97,1413,1447,2860 I must leave the data format the same --but I want a special number from it. In this case it's 97 and it's always going to be the first in the 4 columns of comma delimited items. I can extract with this:

Code: cat datafile | awk -F" " {'print $3'} | awk -F"," {'print $1'} But that's really sloppy. Can someone point out a better way of doing this (with awk) and tell me why?

Software :: Convert Unix Time To 'real' Time

Jan 28, 2010

I used the following command to get the unix time of root user creation:

awk -F":" '$1 == "root" {print $3}' /etc/shadow
How can i convert this into the date/time of creation?

I am writing a shell script, which determines the OS installation date among other stuff, and i am assuming the root user's account creation date should be a pretty accurate pointer. Are there reasons why i should not be assuming so?I would be open to other suggestion for getting this date/time, but it would nevertheless be interesting to convert the unix time to "real" time without doing complex manual(or otherwise) computation..

Programming :: Count The Number Of Slashes In Each Line?

Jan 18, 2010

I have a file with lines that look like this:


And I'm trying to count the number of slashes in each line. I figured (with my limited knowledge of bash) that the best thing to use would be sed. So I ran this to print "not /": sed '!s////g' file # and eventually adding " | wc -m" to it. and I got the same result as if I ran cat, no modification at all:

Server :: Fun With Apache Rewrites Proxies And Trailing Slashes?

Mar 26, 2010

I have a back-end server behind a proxy machine. I would like non-SSL requests to the proxy to be rewritten into HTTPS requests to the back-end server, while not screwing up URLs with missing or misplaced trailing URL slashes. So far, on the proxy side, I have this in a virtual host for port 80:

ReWriteEngine On
# trailing slash fix:
RewriteCond %{SERVER_NAME}$ [NC]
RewriteCond %{REQUEST_FILENAME} -d


But adding anything else to the URL fails, as the back-end server name gets stuck into the proxied [URL]... The rewrite log seems okay, I think. So I guess this is failing at the reverse proxy rule? Where am I going wrong?

General :: DU Style Directory Listing With File Numbers

Sep 6, 2010

Is there a command to return a recursive listing of sub-directories and the number of files in them? I have found plenty of ways to give me the total number of files in a directory structure, but none that gives a list of the sub-directories with the number of files in them. "du" gives me a listing of directories with their sizes, but I couldn't find an option (or any other way) to give me the number of files as well. Ideally, I'd like to get list with "Size" "Files" "Dir name" - And the order of the columns doesn't matter. Is there a "simple" command line solution or do I need a shell script for that?

Programming :: Delete Trailing Slashes Using Bash On-board Means?

Dec 8, 2010

I prefer to delete trailing slahes from pathes. Until now I used sed:

Code: $ myPath=/home/ladygaga///
$ echo "$myPath" | sed 's//*$//'
/home/ladygaga I played around to accomplish the same with on-board means of bash without using sed, but for example this line only deletes one trailing slash:
Code: $ myPath=/home/ladygaga///
$ echo ${myPath%/*}
/home/ladygaga// Is there a way to delete trailing slahes with just on-board means of bash?
