ssh command headache
Good day,
I am trying to run a ssh command on a remote server, but when I run the command the server takes FOREVER... and ends up giving me an error..
then the script also kicks server load up by 100% while it is running..
But if I run the same command on the server it goes pretty quickly and gives the correct std output.
Command on server:
readonly@VCRE02 ~# YEAR=2009;DAY=27;MONTH=02;LMONTH=Feb;for t in 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23; \
do nice -n 20 gunzip -c "/log-archive/access.log_$YEAR$MONTH$DAY_"*$t.gz |nice -n 20 nawk -v a=$t '{total[$8] += 1} END{for (i in total) print a,i, total[i]}' ;done
<std output below>
00 "200" 353061
00 "302" 5001
00 "404" 3689
00 "304" 20030
00 "500" 592
(this of course is what I want..)
ssh command:
Servername=cre02 ; ServerIP=10.113.98.17 ;nice -n 20 ssh readonly@$ServerIP 'YEAR=2009;DAY=27;MONTH=02;LMONTH=Feb;for t in 00 01 02 03 04 05 \
06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23; do nice -n 20 gunzip -c "/log-archive/access.log_$YEAR$MONTH$DAY_"*$t.gz | \
nice -n 20 nawk -v a=$t '\''{total[$8] += 1} END{for (i in total) print a,i, total[i]}'\'' ;done'
<std error below>
gunzip: /log-archive/apache/access.log_200902*00.gz: No such file or directory
gunzip: /log-archive/apache/access.log_200902*01.gz: No such file or directory
gunzip: /log-archive/apache/access.log_200902*02.gz: No such file or directory
gunzip: /log-archive/apache/access.log_200902*03.gz: No such file or directory
gunzip: /log-archive/apache/access.log_200902*04.gz: No such file or directory
(this is not what I want)
I have tried quoting the filename for the "gunzip -c" command in various ways, but is does not really work.
ex. gunzip -c "/log-archive/access.log_$YEAR$MONTH$DAY_"*$t.gz
gunzip -c /log-archive/access.log_$YEAR$MONTH$DAY_*$t.gz
gunzip -c /log-archive/access.log_$YEAR$MONTH$DAY*$t.gz
no luck.
This is a sample filename of the files I am trying to gunzip:
/log-archive/access.log_20090101_00.gz
I noticed if I "cat" the files that have not yet been archived the whole process goes much smoother and there is no issues with the filenames..
So somewhere I am doing something wrong.. and for the life of me I cannot figure out what it is.
Any advise on this will be greatly appreciated.
Thanks.
