how do I write a script that read from this file and replace:

Please assist...greatly... (3 Replies)
Im trying to code some logic into a test script to test for the existence of a file before recreating it. Im using the following line to test for this:
if -r test.txt;
However I get the error message

Having read through the man pages im still not clear whats... (2 Replies)
I have 2 separate Bourne shell scripts with 2 questions in Sun O/S & UNIX environment.
Question 1: One of the scripts is supposed to be executed by "root" user only but cannot be executed after user executes "su - oracle". How can I check in the script whether the current user is "root" user?... (8 Replies)
Guys,
I am writing a script to delete files 5 min old in Sun Os Unix.
find . -name "*.txt" -mtime +1 -print
I could find an equivalent command to look for files which are 5 min old. i tried -mmin option it didn't work either.
Can any body trow a light on this.
Cheers :)

Thanks for keeping such a help-full platform active and live always.
I am new to this forum and to unix also.
Want to know how to count the repetition of a field in a file. Anything of awk, sed, perl, shell script, solution are welcomed.

Hi,
I have a tab delimited file in which first row is the header and others rows has the values.
A B C D
2 4 0.00 3.00
0.00 9.78 4654 898
I have to check whether all the values are zero.
A B C D
0.00 0 0.00 0.00
0.00 0.00 0 0.000
Send mail if all the values in file are zero (4 Replies)
I am suppose to make a program that cuts the extension off of a file. It uses that .ext to decide which program needs to be used to open the file. This only finds the name of the program from a list of programs I made. My problem is when it has the name of the program it needs to use, how can I... (3 Replies)
I have a file number.txt.I need to get 2 inputs from the terminal like a=100 and b=200.If a and b are there in the file,then check if a < b,print "less".If a is not there in the file,print "a is missing" or if b is not there in the file,print "b is missing".

portal(5) File Formats Manual portal(5)NAME
portal - a "window to the future" for applications
SYNOPSIS DESCRIPTION
This header file is a "window to the future" for applications. It will help you to:
o Write code that is portable across 32-bit and 64-bit systems,
o Avoid undocumented assumptions about sizes of integral types,
o Write portable code that needs to be explicit about the sizes of integral types,
o Write code that is portable to a platform which has different sizes of integral types, and
o Share frequently used macros that are portable across 32-bit and 64-bit systems.
In addition to the macros defined in this file, it includes the header files (see limits(5)) and (see inttypes(5)).
The following macros are defined in
This macro can be used to create a mask that has one bit set.
bit_num is the position of the bit to set, and type is the data type of the mask. A -1 is returned in the case of overflow or
underflow.
This macro can be used to set a bit in a mask.
mask is the current value of the mask, bit_num is the position of the bit to set, and type is the data type of the mask.
This macro can be used to return the bit position
of the sign bit for the specified data type. type is the data type for which to return the position of the sign bit.
This macro can be used to return a mask for the sign bit for
the specified data type. type is the data type for which to return the sign bit mask.
This macro can be used to do a sign extension from one
data type to another. value is the current value that is to be sign-extended. old_type is the current data type of value and
new_type is the new data type of value.
This macro can be used to check if code has been
compiled big or little endian. endian is an integer in which the result will be returned.
The following macros can be used for print formatting and scan formatting of values of data types that can change in size based upon the
compilation flag Examples of such data types are off_t and fpos_t.
EXAMPLES
The macro in the following example will turn on the high bit in a 64-bit integer.
The macro in the following example will be used to turn on all bits except the sign bit in a 32-bit integer.
The macro in the following example will turn on the three least significant bits of the maximum integer.
The macro in the following example will return the position of the sign bit in a 32-bit integer.
The macro in the following example will return a sign bit mask for a 32-bit integer.
The macro in the following example will convert the 8-bit integer stored in a char data type to a 64-bit integer and correctly extend the
sign.
The macro in the following example will store a 1 in endian if the compilation was big endian; otherwise, it will store a 0 in endian.
