Hello
I need to run some sed commands but it involves "/" in the substitute or delete, any ideas how I get round the problem.
Example:
cat file1.txt | sed -e '/</Header>/d' > file2.txt
This errors due to the forward slash before the Header text.

Hi,
I've a shell that uses two sed commands to tailor a file.

Hello,
I am very new to Unix and using sed so I'm struggling a little bit with this command and was hoping someone could help me out.
I want to find a nested pattern in a file and replace some text in that file with text from another file.
For example, in file one I have something like... (11 Replies)
Hello, would you please help me with why my SED command file is outputting the entire input file instead of only the text that I'm trying to block?

Ok, this one isn't for everybody, it's pretty tough and I've spent a good deal of time on it without figuring it out yet.
Can anybody get this script to work:

sed "29s/.*/\"$cq_fname\"/" file1.sas >... (3 Replies)
1. The problem statement, all variables and given/known data:
I have to write a script using sed, which delete everything between curly brackets and the brackets themself. The brackets might be nested.

sane-gphoto2(5) SANE Scanner Access Now Easy sane-gphoto2(5)NAME
sane-gphoto2 - SANE backend for gphoto2 supported cameras
DESCRIPTION
The sane-gphoto2 library implements a SANE (Scanner Access Now Easy) backend that provides access to the digital cameras supported by
gphoto2. This backend has only been tested with a handful of cameras so far. Patches to support other models are welcome.
Because of the limited testing of this backend, it is commented out in /etc/sane.d/dll.conf by default. Either the comment character must
be removed or the backend must be called explicitly. E.g. `scanimage -d gphoto2' or `xscanimage gphoto2'.
DEVICE NAMES
The current version of the backend only allows one camera to be connected. The device name is always "0".
CONFIGURATION
The contents of the gphoto2.conf specify the characteristics of the camera to be used. Resolutions (high resolution, low resolution, and
thumbnail size) are required since they are needed by the sane frontends, but can't be obtained through the gphoto2 interface. Valid ports
and cameras can be obtained by "gphoto2 --list-cameras" and "gphoto2 --list-ports".
The dumpinquiry line causes some information about the camera to be printed.
Empty lines and lines starting with a hash mark (#) are ignored. A sample configuration file is shown below:
The "topfolder" line specifies the "fixed" part of the file path. For example, on the Kodak DC-240, files are stored in the directory
/DCIM/100DC240. The /DCIM portion is constant, but 100DC240 will change and must be read from the camera. In this case, the line would
read "topfolder=/DCIM"
Some cameras don't implement a file structure and store all pictures in the "/" directory. This is indicated by setting "subdirs=0" with
"topfolder=/"
port=usb:
camera=Kodak DC240

FILES
/etc/sane.d/gphoto2.conf
The backend configuration file (see also description of SANE_CONFIG_DIR below).
/usr/lib64/sane/libsane-gphoto2.a
The static library implementing this backend.
/usr/lib64/sane/libsane-gphoto2.so
The shared library implementing this backend (present on systems that support dynamic loading).
ENVIRONMENT
SANE_CONFIG_DIR
This environment variable specifies the list of directories that may contain the configuration file. Under UNIX, the directories
are separated by a colon (`:'), under OS/2, they are separated by a semi-colon (`;'). If this variable is not set, the configura-
tion file is searched in two default directories: first, the current working directory (".") and then in /etc/sane.d. If the value
of the environment variable ends with the directory separator character, then the default directories are searched after the explic-
itly specified directories. For example, setting SANE_CONFIG_DIR to "/tmp/config:" would result in directories "tmp/config", ".",
and "/etc/sane.d" being searched (in this order).
SANE_DEBUG_GPHOTO2
If the library was compiled with debugging support enabled, this environment variable controls the debug level for this backend. A
value of 128 requests maximally copious debug output; smaller levels reduce verbosity.
GP_DEBUG
Set to 1, 2, or 3, to enable various levels of debugging within the gphoto2 libraries.

BUGS
Many, no doubt.
More general comments, suggestions, and inquiries about frontends or SANE should go to the SANE Developers mailing list (see
http://www.sane-project.org/mailing-lists.html for details). You must be subscribed to the list, otherwise your mail won't be sent to the
subscribers.
