I am using under-noted script and getting the error as under. Please help.
Executing each individual cat / gzcat gives correct answer.
Code:
gzcat /logs/1205[01]* gzcat /logs/12052[0123]* cat /logs/12052[456789] | egrep -v "XYZ|PQR"|wc -l
gzcat: gzcat.gz: No such file or directory
gzcat: cat.gz: No such file or directory
gzcat: /logs/120524.APX: not in gzip format
gzcat: /logs/120525.APX: not in gzip format
gzcat: /logs/120526.APX: not in gzip format
gzcat: /logs/120527.APX: not in gzip format
gzcat: /logs/120528.APX: not in gzip format
gzcat: /logs/120529.APX: not in gzip format

The errors come from the syntax usage which wants the command followed by options if any then [name... ]
so looking at your command line you get:
Code:
gzcat (the command) [ no options] [name1:/logs/1205[01]*] [name2: gzcat] [name3:/logs/12052[0123]*] [name4:cat] [name5:/logs/12052[456789] ]
You see here that name2 and name4 are the two first "errors"
name5 the list of non gzip format files that you knew werent for you used cat to list if it did work that way...
But it doesnt..., look at the man pages!

Thanks..any feasible option to execute cat also, as i have both type of files in the directory and processing them seperately will add to double efforts.
Hey guys,
I want to do something quite simple but I just can't no matter what I try. I have a large file and i usually just:

But now I need to do it only for the first 100k records. I sure... (7 Replies)
Hi all
Is there a way to read and process a gzip file line by line similar to a text file without using gzcat..
while processing a text file we will usually use the logic
exec<sample.txt
while read line
do
echo $line
done
Is there a similar way to process the gz file in the same... (4 Replies)

I am trying to write a script that prompts users for date and time, then process the gzip file into awk. During the ksh part of the script another file is created and needs to be processed with a different set of pattern matches then I need to combine the two in the end. I'm stuck at the part...

Does anyone know what kind of impact gunzip -c or gzcat has on a system? I am using gunzip -c on files that around 30 Mb compressed and 300Mb uncompressed. How much memory or disk space gets used? Also does anyone know how gunzip -c actually works? The system I am running on is AIX Version 5.
