I am trying to edit a large bunch of files. Each file has four columns and I want to get rid of the first one, but in each line the number of the first column changes. the number in the first column ranges from 1 digit to 5. For example
1 aaaaa bbbbbb ccccc
23 aaaaa bbbbbb ccccc
15343 aaaaa bbbbbb ccccc
and the desired format would be
aaaaa bbbbbb ccccc
aaaaa bbbbbb ccccc
aaaaa bbbbbb ccccc
Suppose the cursor position line at bottom or top. What's the vim command to get the cursor position line at the mid of the windows in vim?

I'm trying to make another file annotation script a little speedier than it has been by the up-until-now proven method of checking the last four characters in a filename before the "dot" (eg .jpg, .psd) against a list of known IPTC categories and Exiv2 command files. It occurred to me that if one script generated a list of files in directory foo, and the same or another script sorted that list by that four-letter tag,then that list could be used(instead of a for/do/done loop on the real files in the folder) by the command-file-matching script to "vomit out" which annotator file would go with file nastynewfile.jpg, f'r'instance. The script I had been using for this task looks like this:
Code:
while read 'line';
do
sp=$(echo $line)
vc=$(echo $sp | cut -d"," -f1)
cv=$(echo $sp | cut -d"," -f2)
[code]....
Where I seem to be stuck is with how to sort the lines in templist, which may be any number of different lengths, from back to front. sort -k looked promising, except it seems only to work the other way round. I thought of invoking a
Code:
q=$(expr length $line); echo $q
n=$[q-8]; echo $n
kind of thing, but that presented the problems of how to sort by those, how to tell sort where to find them (grep?) and how to "stitch them back in" to the original list, which is what I want to sort in the first place.

View 2 Replies View RelatedThe objective is to read a file line by line, add a tab at end of each line and add a value(number) after the tab.
My script:
Code:
Report.tsv before running the script for the first time:
Code:
At the end of first run, each line of Report.tsv gets appended by a space instead of a tab. On the other hand each line of Report.tsv gets appended by tab at the end of second run onwards.
This was realized when Report.tsv was imported in open office spreadsheet. First set of appended values get merged into the original column (Strings) and the subsequent appended values fall in distinct columns.
got a situation where if i process a command i get a numeric output something like below:
for example:
# cat example.txt
856589
856470
987866
656658
876897
now i want to see this output in single line like below:
856589 856470 987866 656658 876897
how do i get this?
How can I figure out which programs are using up swap space? My current memory usage is 2.9GiB out of 3.0GiB used(and I though I had 4GB, I need to check into that) and 1.3Gib of swap used.
View 1 Replies View RelatedI have a linux server top reports about 9GB of swap used:But I cannot figure where's it use swap, some google results said that top - O commad follow by p will show swap usage by process. But as shown in the above image, taking a brief sum of the SWAP column shows that > 10GB of swap is used, so where does the 9GB figure for swap usage come from? Top reports that about 96492kb of ram is used by buffers. Is there anything I can do to utilize this, instead of using swap?

Any ideas how I can find which files are suddenly taking up the space?
We have recently built some RAC (OS:RHEL55) servers and after the Oracle guys have installed their application, somehow the directory / is using the maximum space. I contacted the Oracle team & they say that their RAC installation doesn't create any files in the / directory. This is the o/p of '/' directory file system:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/datavg-vol2 498M 382M 62M 88% /
Also, when I checked the file sizes, I found that the following files were taking more space:
/etc/selinux/targeted/modules/active/
-rw------ 1 root root 17M Nov1 base.linked
[code].....
I don't know what these files are doing there, when I did a cat and cheked, I found the files containing this data:
nf_tre--
stem_dbusd_var_run_t...and some stuff like this Unable to decide whether or not to remove these files. Also, is there any way to find out what files are taking more space and whether they can be deleted or not? in order to free up some space in the / direcoty. As there are 10 RACs that we've build, I got to do something to fix this for all of the 10 servers.
I want to find all users shown in the /home/ directory whose disk consumption is more than 500MB. The following command works as expected.
cd /home/ && du */ -hs

From the above example, only 902M john/ should be returned.
How can I make the find command output the same results?
Logical Memory Space of 4GB is divided in to 3GB User Space and 1GB Kernel Space. Always. Correct?
1. How can we change it? (just changing value of PAGE_OFFSET is okay?)
2. If system have only 256MB of memory (embedded system) and suppose Kernel Modules eat away all the memory during boot. User space will be left will no memory. Is this case possible?
I have a perl/python interpreter available on the system so really as long as the script would run on a standard linux build I'll be happy.So I don't know how to program a script that would find the unique key (which if needed, can be easily stripped out and put into a separate file) and then print out the data below it without going into the other lines.
View 4 Replies View RelatedI need to find each line in a file which does NOT begin with a double quote (") and append that line to the previous line. I have been successful doing this using the following command:
cat filname.csv | sed -e :a -e '$!Ns/
[^"]//;ta -e 'P;D' > newfilename.csv
My issue is the substitution. As you would expect after the line is appended to the previous line the first character is removed. I need it to not be removed. I tried:
cat filname.csv | sed -e :a -e '$!Ns/
[^"]/&/;ta -e 'P;D' > newfilename.csv
but it just hangs.
Goal:
Input:
"line 1"
line 2
Output with existing sed command is:
line 1ine2
I need it to be line1line2.
SuSE SLES10, 32 bit. I have an app which crashes with general protection often.
There is message every time in /var/log/messages:

How do I establish relation between this message and source code? Error was observed on another host where some tests were running, now license is expired and I can't get more info nor core dump. I have to investigate what I have and try to reproduce it locally. Unfortunately original binary was stripped.Now I prepared non-stripped version. Does it has the same addresses for function as original? Is it possible to use symbol information for finding where RIP points to?
