Hi all,
I am having a bit of a hard time using awk. I must do something wrong, but I don't know what... Any help would be greatly appreciated!
I read a file, as follows :
It has thousands of lines like this. I wish to sort some data out, but only when column 5 (here an "A") is within a range of letters accessible via the variable data. data is a user input and can be any letters in the range A-Z, in any combinaison (i.e. "F", "ABCFIZ", "A-GX", "KJHGF", ...). So I do this :
That it is not working. If I put a single letter (e.g. $5 == "A"), it works just fine, but as long as I want a variable, it doesn't output anything. I tried A LOT of combinaison around the metacharacters [] , like : "'[$data]'", "'['$data']'", "'\[$data\]'", "'["$data"]'", etc and nothing works - and often yielded errors. I'm out of ideas, if anyone has a suggestion...
I may add, for precision sake, that the quoted awk code is within a much longer script, called from and programmed into tcsh.
Hi All,
I would like to assign the following values to each column in my file.
if $i is between 1 and -1 (ie -1 < $i < 1) then print A;
if $i is between -2 and -1 && 1 and 2 (ie. -2 < $i < -1 && 1 < $i < 2) then print B;
if $i is between -3 and -2 && 2 and 3 (ie. -3 < $i < -2 && 2 < $i < 3)... (1 Reply)

truncate
TRUNCATE(1) User Commands TRUNCATE(1)NAME
truncate - shrink or extend the size of a file to the specified size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole)
reads as zero bytes.
Mandatory arguments to long options are mandatory for short options too.
-c, --no-create
do not create any files
-o, --io-blocks
treat SIZE as number of IO blocks instead of bytes
-r, --reference=RFILE
base size on RFILE
-s, --size=SIZE
set or adjust the file size by SIZE bytes
--help display this help and exit
--version
output version information and exit
The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (pow-
ers of 1000).
SIZE may also be prefixed by one of the following modifying characters: '+' extend by, '-' reduce by, '<' at most, '>' at least, '/' round
down to multiple of, '%' round up to multiple of.
