It's not what I expected, but it's a nice and simple solution. Did not know why it didn't occur to me... I was stubborn in use an "args" variable, that I didn't realize there was a much simpler...

Hi,
I need to get input arguments, as well as validate them. This is how I'm reading them:

#!/bin/bash
args="$@" # save arguments to variable
## Read input arguments, if so
while [ $# -ge...

It worked!! Thanks a lot.

Can you tell me why 'eval' is necessary and my command did not work without it? I don't understand why.

Anyway, I really appreciate your answer. It saves me a lot of...

Thanks both.
I already tried as you both say and it doesn't work, either. I also tried using single brackets, and nothing. It looks like it is unable to substitute $LIB_HOME by its content.
Even...

Hi,
I'm trying to figure out whether some files exist. Locations of those file are stored in a plain text file called temp.txt in this way:
All environment variables ($LIB_HOME and $ORACLE_HOME)...

Yes, first convert file, then rename it.
iconv -f ISO-8859-1 -t UTF-8 /loc/test.txt > /loc/test.tmp; mv loc/test.tmp /loc/test.txtYou must be careful, because you'll overwrite original file. First,...

Try iconv command:

Uff, it's too much work.
There are more than 20 thousand lines in that file, and not all of them has the same pattern.

I just wonder why similar commands had different output. I thought awk and...

Hi,

This is the first line that fails (awk only prints 7 characters, although awk output is 8 characters length, 7 zeros and a blank):
Whole line length is 546, but I don't know how post line...

Hi all,

I want to get each line of a data file from position 464 plus 8 characters. I tried in two different ways, and the results were different. I'd like to know why.

First method, using...

Yes, indeed. Both really help!
Thanks.

By the way, I forgot to tell you I was using cygwin to run those commands and scripts, although it probably doesn't make any difference in all you told...

Hi,

vivek d r, I actually didn't make an script. I just ran whole script from command line, preceded by time, ie:
rbatte1, I undestand that you recommend me to learn awk for scripting?
I ran...

Hi all,

In bash scripting, I use to read files:
cat $file | while read line; do
...
doneHowever, it's a very slow way to read file line by line.
E.g. In a file that has 3 columns, and less...

The command is du:
For example: if you want to get how much space is used by each subdirectory you can do something like:
find . -maxdepth 1 -type d | xargs du -m -sThis command finds each...

I think something like this should work:


ls A/. | while read line; do
filename=`echo $line | cut -d '.' -f1` # gets filename without ext
if [ -f B/$filename.tar.gz ]; then # cheks...

What do you wanna do?
Exit causes the shell to exit.
Exit an 'if condition' has no sense, unless you are inside a loop. Just change condition, from "equals" to "not equals". For example:

if [...

Hi,

In script I posted I checked whether a line is in the other file. To do that I just check its length. If length is 0 it means grep has no output. So, that line is not in file2, and it can be...

I suggest to get a shell reference, if you need to program scripts often. In bash: GNU bash manual - GNU Project - Free Software Foundation (FSF) (http://www.gnu.org/software/bash/manual/), available...

Toad can do that for you.
Select schema browser view ==> Right click on table ==> Save as...

Is this enough?

Won't be easy using diff?
Anyway,
cat file1.txt | while read line; do
if [ -z "`grep "$line" file2.txt`" ]; then
echo $line >> file3.txt
fi
doneAlbert.

I apologize, because it seems to be my mistake. I'm not able to reproduce such wrong behaviour. So, that means I made a mistake when I typed the command. I think the mistake could be because I could...

You are right. I've just checked it in my own Ubuntu at home and it works.
I don't know which command in CentOS has the problem. It is strange thing, isn't it?


Yes, I already tried it. But it...

Hi all,

I'm wondering why this command does not work, at least, as I expect:
find . -type f -mtime +7 -print0 | xargs -0 ls -lI expect that it list all files older than 7 days, with all...

I can't do that because it will replace all List<..> occurrences, and project won't compile.
Only javadoc comments where generic begins with an "A" must be replaced. It's there where bug makes...

I'll try to ask the question in other way. In my Java file I have a line with this text:
