You are correct in noting that you need to use strings when looking for a string in a binary file. The grep utility is only defined to work on text files. This may not be highly efficient, but it should do what you want. First create the following shell script as a file named $HOME/bin/st_gr_pr:
and make it executable using the command:
Note that the -i option to the grep command in this script makes searches for alphabetic characters case insensitive. I use ksh, but bash should also work if you want to use it in this script.
Then run the command:
to get a list of all regular files rooted in the current directory that contain srv6000, SRV6000, or any of the other six strings with combinations of uppercase and lowercase s, r, and v in that order. Obviously, replace srv6000 if you want to find files containing a different pattern.
please let me know that in unix using c programming language we can do binary to string conversion and vice versa using ltoa and atol but how can we do it in c++ programming language.
thank you in advance. (3 Replies)

Hi,
I have a problem that I am sure someone will know the answer to. Currently I have a script which returns a binary output if it finds a certain search string (in this case relating to a DRBD cluster) as follows:

Hi All,
Iam new to unix scripting and I want a split a string into 4 characters each, leaving the last two characters and convert the splitted values into binary.
For example:
string='ffd80012ffe20000ffebfffeffea0007fff0ffd70014fff1fff0fff0fff201'
this should split as
ffd8
0012
ffe2

I am struck up with a problem and that is with output redirection.
I used all the ways for the redirection of the output of c binary to a file, still it is failing.
Here are the different ways which I have used:
./a.out | tee -a /root/tmp.txt 2>&1
./a.out | tee -a /root/tmp.txt 1>&1

BINFMT.D(5) binfmt.d BINFMT.D(5)NAME
binfmt.d - Configure additional binary formats for executables at boot
SYNOPSIS
/etc/binfmt.d/*.conf
/run/binfmt.d/*.conf
/usr/lib/binfmt.d/*.conf
DESCRIPTION
At boot, systemd-binfmt.service(8) reads configuration files from the above directories to register in the kernel additional binary formats
for executables.
CONFIGURATION FORMAT
Each file contains a list of binfmt_misc kernel binary format rules. Consult binfmt-misc.rst[1] for more information on registration of
additional binary formats and how to write rules.
Empty lines and lines beginning with ; and # are ignored. Note that this means you may not use ; and # as delimiter in binary format rules.
CONFIGURATION DIRECTORIES AND PRECEDENCE
Configuration files are read from directories in /etc/, /run/, and /lib/, in order of precedence. Each configuration file in these
configuration directories shall be named in the style of filename.conf. Files in /etc/ override files with the same name in /run/ and
/lib/. Files in /run/ override files with the same name in /lib/.
Packages should install their configuration files in /lib/. Files in /etc/ are reserved for the local administrator, who may use this logic
to override the configuration files installed by vendor packages. All configuration files are sorted by their filename in lexicographic
order, regardless of which of the directories they reside in. If multiple files specify the same option, the entry in the file with the
lexicographically latest name will take precedence. It is recommended to prefix all filenames with a two-digit number and a dash, to
simplify the ordering of the files.
If the administrator wants to disable a configuration file supplied by the vendor, the recommended way is to place a symlink to /dev/null
in the configuration directory in /etc/, with the same filename as the vendor configuration file. If the vendor configuration file is
included in the initrd image, the image has to be regenerated.
EXAMPLE
Example 1. /etc/binfmt.d/wine.conf example:
# Start WINE on Windows executables
