Hi,
Was wondering if you could give me an example of extracting a 10 digit number from 5 txt files using a regular expression (the number is always different ) and storing the numbers in variables
Thanks

i am new to shell scripting. i want to keep on increamenting a 6 digit number. For eg. 000000 + 1 = 000001 But instead of 000001 i get only 1. How do i do this ? Pls help. (8 Replies)
I have to write a c program which takes a 3 digit number n and calculates the value of (2^n)+1 and then determines the number is prime or not.
I have tried to first calculate the value of 2^n and then adding one to it and then apply the logic of prime number.
but the ultimate problem is that... (7 Replies)
Hello. I have 9060 files labelled File1 to File9060. They are in numerical order. When I grep a file eg. File90 it will show me all files that contain the pattern "File90", eg File901 or File9001. I can only get specific files for File1000 or higher. How can I resolve this problem? Is there a... (5 Replies)
I want to write/print a number through a shell script up to its last significant digit (LSD) after the decimal point.
Say,
x=10.00056000000000000
I want to print x as x=10.00056.
Note that x can be any thing so I cannot know the position of the LSD always.
Thanks. (16 Replies)
Dear All,
Lets say I have a number with following format:
####.12e-##
now I want to compare place holder in position 1 and 2.
How can I do that?
Note: My number is stored in a variable say var.
example:
var=9999.12e-05

ldd
LDD(1) Linux Programmer's Manual LDD(1)NAME
ldd - print shared object dependencies
SYNOPSIS
ldd [option]... file...
DESCRIPTION
ldd prints the shared objects (shared libraries) required by each program or shared object specified on the command line. An example of
its use and output is the following:
$ ldd /bin/ls
linux-vdso.so.1 (0x00007ffcc3563000)
libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f87e5459000)
libcap.so.2 => /lib64/libcap.so.2 (0x00007f87e5254000)
libc.so.6 => /lib64/libc.so.6 (0x00007f87e4e92000)
libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f87e4c22000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f87e4a1e000)
/lib64/ld-linux-x86-64.so.2 (0x00005574bf12e000)
libattr.so.1 => /lib64/libattr.so.1 (0x00007f87e4817000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f87e45fa000)
In the usual case, ldd invokes the standard dynamic linker (see ld.so(8)) with the LD_TRACE_LOADED_OBJECTS environment variable set to 1.
This causes the dynamic linker to inspect the program's dynamic dependencies, and find (according to the rules described in ld.so(8)) and
load the objects that satisfy those dependencies. For each dependency, ldd displays the location of the matching object and the (hexadeci-
mal) address at which it is loaded. (The linux-vdso and ld-linux shared dependencies are special; see vdso(7) and ld.so(8).)
Security
Be aware that in some circumstances (e.g., where the program specifies an ELF interpreter other than ld-linux.so), some versions of ldd may
attempt to obtain the dependency information by attempting to directly execute the program, which may lead to the execution of whatever
code is defined in the program's ELF interpreter, and perhaps to execution of the program itself. (In glibc versions before 2.27, the
upstream ldd implementation did this for example, although most distributions provided a modified version that did not.)
Thus, you should never employ ldd on an untrusted executable, since this may result in the execution of arbitrary code. A safer alterna-
tive when dealing with untrusted executables is:
$ objdump -p /path/to/program | grep NEEDED
Note, however, that this alternative shows only the direct dependencies of the executable, while ldd shows the entire dependency tree of
the executable.
OPTIONS --version
Print the version number of ldd.
-v, --verbose
Print all information, including, for example, symbol versioning information.
-u, --unused
Print unused direct dependencies. (Since glibc 2.3.4.)
-d, --data-relocs
Perform relocations and report any missing objects (ELF only).
-r, --function-relocs
Perform relocations for both data objects and functions, and report any missing objects or functions (ELF only).
--help Usage information.
BUGS
ldd does not work on a.out shared libraries.
ldd does not work with some extremely old a.out programs which were built before ldd support was added to the compiler releases. If you
use ldd on one of these programs, the program will attempt to run with argc = 0 and the results will be unpredictable.
