I have a program that takes a relative path as input appends it to a some path string to get the actual path.
Now all I can input is the relative path. So if I want to go one level above my input will be ../mypath.
If I know the depth of the path used internally, I can use .. as many times to go to the root directory and then give the absolute path. But suppose I do not know the depth of the directory, can I construct a relative path string such that it considers it as a relative path. One way could be to have enough .. in the path string so that I can force an absolute path for some maximum depth of path.
Is there some path string syntax that I am not aware of but can achieve this?
prefix=user@my-server: find . -depth -type d -name .git -printf '%h�' | while read -d "" path ; do ( cd "$path" || exit $?
[code]....
How shall i go about changing the absolute path to relative path, so that /home/git/mirror/android/adb/ndk.git gets converted to /mirror/android/adb/ndk.git //echo <command> "$prefix$PWD.git" ?? - anything for relative path?
Java applet not loading image with relative path(e.g. images/1.jpg) but loads image with absolute path(i.e. from /root/user/images/1.jpg) . This is a problem when i want to host the applet on web server
I mostly do .Net development in a Windows 7 virtualbox. I use the host for simple things such as web browsing, skype, chat, etc. All things that are fantastically available on Ubuntu which I in many ways prefer. So this has been begging the question for a while: why even use Windows on the host, seems like a Linux host would use less resources (untested) and allow my Windows VMs to run better while allowing me to do my non-development stuff in an interface I prefer.
So easiest way to do this - I downloaded wubi and installed Ubuntu. I installed in it Virtualbox, and then start add and start my VM to get this message: Failed to open a session for the virtual machine VS2010, Could not open the medium '/host/Users/George Mauer/Virtualbox VMs/VS2010/C:/Users/George Mauer/.VirtualBox/HardDisks/VS2010.vdi; VD: error VERR_FILE_NOT_FOUND opening image file '/host/Users/George Mauer/Virtualbox VMs/VS2010/C:/Users/George Mauer/.VirtualBox/HardDisks/VS2010.vdi; (VERR_FILE_NOT_FOUND).
You see what's going on? With wubi, the windows drive gets mounted at /host/ but virtualbox is for some reason appending an absolute path! I would very much like to use the same exact VM file since it would retain Snapshots and I would be able to use it in either windows or Ubuntu mode. However, even if I try to simply mount the drives into a new VM I get an error: Failed to open the hard disk /host/Users/George Mauer/.VirtualBox/HardDisks/VS2010.vdi. Cannot register the hard disk '/host/Users/George Mauer/.VirtualBox/HardDisks/VS2010.vdi' {guid...} because a hard disk '/host/Users/George Mauer/VirtualBox VMs/VS2010/C:/Users/George Mauer.VirtualBox/HardDisks/VS2010.vdi with UUID {guid...} already exists.
This is especially odd since this worked fine with my recently created Android VM, though this might have something to do with the fact that VirtualBox recently changed their default VM storage locations. Any idea how to fix this? My Linux-fu is weak but I seem to remember from CS class something about symbolic links that might be relevant here?
As it's result command creates file /backup/snapshots/backup/databases/mysql.sql. How can I force it to put file in /backup/snapshots/mysql.sql? It's mandatory that source must be remote (it's part of more complex script).
Does anyone know how to get the path with a inode number by C programming? Or can I get the absolute path without giving a "path" but a inode number by C?
like this: get_path(unsigned inode); not such this function: getcwd(".", xxx); taowuwen@gmail.com
Given that I want my shell script be invoked at the command line using the above parameters - where [these brackets] denote that they are optional - what is the best method to parse them?
I am looking for a powerful command line tool to send and receive data via socket I mean define IP , port and data other options for command to send and receive data from sender.(like a high level socket programming)
I wanted to read out the absolute file-path (filename) as sorted in a folder (on Linux). The reading the file-paths is ok but I have problems in sorting.
Code:
selectedDirectory = fl_dir_chooser ("Select Imagedirectory:",NULL,0); //This is just a widget to show the folder. DIR *d; dirent *de;
[code]....
The files -105.dcm, -106.dcm, -107.dcm lie in the folder at the bottom and -36.dcm, -37.dcm- at the top. The program compares 1 and 3 of 105 and 37, 1 is lesser than 3, then prints out first, but does not know that 105 is three digits and 37 is two digits.
I need to extract the absolute directory from the type command when I pass it a program name. E.g.
Code:
>type cat cat is hashed (/bin/cat)
There is one other case (I believe):
Code:
>type lpr lpr is /usr/bin/lpr
I thought of using regex, but it returns the whole line, not just the match. In addition, there is no option cited in the man page for type that returns just the command directory.
Note: this is part of my solution to a programming assignment in bash shell scripting.
I have a quick question: how can I make the path short on the console? My problem is that if I descend 10 levels in a directory tree, the path becomes so long that it takes more, than one line of the console window. Is there a way to shorten it, and show only the name of the current directory, without the whole path, i.e., instead of
Code: v923z@penguin: first/second/third/fourth/fifth/sixth/seventh/eighth/ninth/tenth> only
If say, I want to read the input given by user at the command prompt and write a code to execute the cmd given then which commands do i use to implement this ( Im writing the code in C )?
Does anyone know a method of being able to process the complete and literal command line passed to a shell script ? I want to have the command line parameters with ALL characters (including meta characters e.g. $ literally).
So as if there was no shell to substitute or expand parameters nor applying it quoting rules.
I want to have a choice or more preferable pass shell as command line argument when I ssh to an linux account.i.e. If John logs in to account "zzz" on server "abc", by default definition of account "zzz" n server "abc" he get csh.But Sally desires that when she logs in to account "zzz" on server "abc", she needs the login shell to be ksh,and Rick wants bash when he logs in to account "zzz" on server "abc".What is the most non-intrusive / easiest way to achieve this? Each user can set their preference on ssh command line or create a simple alias by each shell, but not sure how to do this.
I am very new to shell scripting.How does one pass a command-line parameter to a shell script?for the below program #/bin/bash mount -t cifs -o user=ramkannan,password=Linux123@ //10.200.1.125/ramkannan /MT cd /MT/test date=`/bin/date "+\%Y-\%m-\%d-\%H-\%M-\%S"` mysqldump -uroot -pram2@ employeedb > $date.sql gzip $date.sql
I want to pass parameter for everything,i tried in google and did but iam getting error while passing parameter to all
#/bin/bash mount -t cifs -o user=$1,password=$2 //10.200.1.125/ramkannan /MT cd /MT/test date=`/bin/date "+\%Y-\%m-\%d-\%H-\%M-\%S"` mysqldump -uroot -pram2@ employeedb > $date.sql gzip $date.sql
i was getting error while passing parameter to all.
I'd like to say I'm very impressed with Fedora 11. I'm a long time Linux user and I've tried many distros. But, I usually keep only the best on my laptop. For a long time that was Ubuntu but, I think Fedora 11 has made some key improvements over Ubuntu and I'm eager to switch. The problem is: I haven't been able to run Fedora as anything other than on the Live CD. Everything works perfectly and it installs but, when I reboot, Grub begins. Instead of booting, however, Grub drops into its minimal shell and gives me a command line.
I've tried installing it a number of ways now and have read much about the problems with Ext4 on Grub and took special care to see that Grub has its own, separate, /boot ext3 partition. Even then, no luck. My hardware should work fine. I've got an HP DV-5 with 4GB RAM, AMD Turion 64-bit dual-core @ 2 Ghz, and an IDE 250GB hard drive. I'm working with the 64-bit Fedora 11 Live disc with KDE as the Gui.
I wonder if there is anyway to make a user-defined bash shell function global, meaning the function can be use in any bash shell scripts, interactively or not. This is what I attempted:
Trying to create a small script that will read user's input, test if user entered some input and if not display some message or display a text using user's input.
The script is the following but i get an error saying "[: 6: =: argument expected"
I've been looking around the net for executing a shell script. My basic understanding is that after setting executable permissions and providing a path (#!/bin/sh) in the first line of the script, I can type ./myscript to execute instead of sh myscript. This is not working for me. I can run "sh myscript" but not "./myscript" even though I know for sure I have across the board execute permission and my sh path is correct. I'm working on a redhat linux station.
