I have a script problem that I am not able to solve due my very limited understanding of unix/awk.
This is the contents of test.sh
awk '{print $1}'
From the prompt if I enter:
./test.sh Hello World
I would expect to see "Hello" but all I get is a blank line. Only then if I enter "Hello... (2 Replies)
Hello!
I have written this script:
for file in "$( find $dirName -type d )"
do
echo "$file"
echo "hello"
done
but as a result I get all the directories and in the end the work "hello". Shouldn't it print the word "hello" after printing the name of each directory and not in the end?

Hello all,
Here is what my bash script does: sums number columns, saves the tot in new column, outputs if tot >= threshold val:
> cat getnon0file.sh
#!/bin/bash
this="getnon0file.sh"
USAGE=$this"
InFile="xyz.38"
Min="0.05"

Hi,
I have a situation to compare one file, say file1.txt with a set of files in directory.The directory contains more than 100 files.
To be more precise, the requirement is to compare the first field of file1.txt with the first field in all the files in the directory.The files in the... (10 Replies)

Hi Experts,
I am trying to get system output to capture inside awk , but not working:
Please advise if this is possible :
I am trying something like this but not working, the output is coming wrong:

Thanks, (5 Replies)
Hi,
I am trying to pass awk field to a command line executed within awk (need to convert a timestamp into formatted date).
All my attempts failed this far.
Here's an example.
It works fine with timestamp hard-codded into the command
echo "1381653229 something" |awk 'BEGIN{cmd="date -d... (4 Replies)
Hi,
I am studying an awk command:
awk '{ sub(/\/\/.*/, "", $NF); print }' input.txt
The input.txt is:

The output is :
char*s1="//hello";
/* hello (2 Replies)

sum
sum(1) General Commands Manual sum(1)NAME
sum - Displays the checksum and byte count in block-size (1024) units of a file
SYNOPSIS
sum [-o | -r] [file...]
The sum command reads file and calculates a 16-bit checksum and the byte count in block-size (1024) units in the file. If the file argu-
ment is omitted, sum reads standard input.
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
sum: XCU5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
OPTIONS
[Tru64 UNIX] Uses an algorithm to compute the checksum using word-by-word computation. Uses an alternate algorithm to compute the check-
sum (rigorous byte-by-byte computation rather than the word-by-word computation).
[Tru64 UNIX] This is the default.
OPERANDS
The file for which a checksum is to be computed. If this operand is omitted, standard input is used.
DESCRIPTION
The checksum and number of blocks are written to standard output. The sum command is generally used to determine if a file that was copied
or communicated over transmission lines is an exact copy of the original. The sum command writes the space used in 1024-byte units.
[Tru64 UNIX] The checksum is calculated using a rigorous byte-byte computation by default.
System V Compatibility
[Tru64 UNIX] The checksum algorithms for the default sum command and the SVID 2 compliant sum command are reversed. The SVID 2 compliant
sum command uses the word-by-word algorithm by default and uses the byte-by-byte algorithm if you specify the -r option on the command
line.
NOTES
The sum utility is marked LEGACY in XCU Issue 5. [Tru64 UNIX] The default algorithm is no longer the word-by-word computation algorithm.
It was changed to the 4.3BSD default algorithm. The algorithms used may not be portable, that is, the same checksum may not be produced
for the same input on different systems. Portable applications should use cksum.
EXIT STATUS
The following exit values are returned: Successful completion. An error occurred.
EXAMPLES
To display the checksum of datafile and the number of blocks in this file, enter: sum datafile
If the checksum of datafile is 1605 and if the file contains 3 blocks, sum displays: 1605 3 datafile
ENVIRONMENT VARIABLES
The following environment variables affect the execution of sum: Provides a default value for the internationalization variables that are
unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari-
ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value,
overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes
of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale for the for-
mat and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of
LC_MESSAGES.
