There are a few problems here. If this script is in the directory where you are looking for and changing occurrences of "./x.mak", one of the files it will try to modify is itself (in at least two...

Hi agama,
When I tried your scripts, the headers came out fine, but all of the data fields were zero:
x_a, A, BX, C,DYY, E, F, G, H, I, J
1_a, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
2_a, ...

@agama, don' think ksh supports the substring expansion and certainly bash will evaluate the length field so ${infile:0:len-4} is acceptable.

Then what you read is either a pedagogical simplification or an oversight. Since the statement, "free() doesn't return memory to the system", is true for 4.4BSD [see Note 1], and since The Design and...

works great.

Thanks.

agama,

Thanks. I ran that command as you suggested and it gave back no input. I am using a spreadsheet editor to make the CSV file so I am positive that there is data in column 7 for every row. It...

You can take advantage of the fact that awk automatically prints given a true expression to reduce the complexity:

awk '$2<0.5{$2="0.50"} $2<1.0' file1 > file2

sed -E uses ERE, so it should know alternation:
sed -E 's/abc=123([^0-9]|$)/abc=999\1/g'

agama said he found a # by itself on a line as the section separator. When I copied the sample input and fed it through od -cb, I found that the separator line contained the octal byte values 343,...

Either one of these should give you the counts your looking for:
sort -u -k1,1 -k3,3 t | cut -d' ' -f3 | awk '{a[$2]++} END{for(e in a){print e FS a[e]}}'
sort -u -k1,1 -k3,3 t | cut -d' ' -f3 |...

No. What you say is true for a BRE; not for an ERE. Quoting from IEEE Std. 1003.1-2008, P190, L6174-6183:

Of the rcp(1) man pages listed on this site, only the Solaris man page specifies exit codes. That man page also has the following warning:

Your function looks OK, but it can't work if the command...

In Solaris, /usr/bin/grep does not support -q flag. Try to use /usr/xpg4/bin/grep, see man page for details.

You need to test the return status ($?) for the /usr/xpg4/bin/grep 'cos it does not...

Another option maybe:
awk -F\| '/ 500$| 202$/{if($13 in A)print A[$13] RS $0; else A[$13]=$0}' infile | sort -t\| -k3,3n

That's a one-liner in name only. In the future, please use a reasonable coding style instead of such a long line. It will make your code easier for novices to understand, and members not using a 2560...

Looks like there's a little bit more to it than that. Fields 2 and 3 need to be cut. I suppose you can pipe cut into sed or just do it in sed itself.

It's never a good idea to withhold information. Better too much than too little. I've lost count of how many times I've seen someone ask for help on some very specific task, and then, later add...

That's awesome. Thank you so much.

@ agama, there was just one little typo:

A much less readable and maintainable version of agama's solution which is guaranteed to make whoever inherits the code mutter under their breath:

date +%s (seconds since the epoch) is also a GNU extra to the date command.

Oops something seems to be missing here try:

#!/bin/sh

if [ `date +%d` -eq `cal | awk '$NF{E=$NF} END{printf E}'` ]
then
rm /home/user/tst/logs/* && rm /home/user/tst/stats/*

exit 0

Well that was not very constructive.

Here you go:

awk '
NR==1{ printf("%20s\t%10s\t%10s\n", $1,"+ve Cr","-ve Cr")}
NR>1{ if($2>0) sumPos[$1] += $2;
else sumNeg[$1] += $2;
