1. when we run od command it displays octal values. But the first column will be always 000000. after that the actual file contents are displayed. Can anyone tell the meaning of that.
2. When we run ls -l command, in the first line of the output, we can see some integer value. What is the significance of that value.
i use this script to get the time and date of back and fourth transactions for a particular execution id. I use a substr command on the 5th column to to cut the milli seconds off the time value. - otherwise the times would look like 08:30:04.235
grep <executionID> <auditfile> | awk '{ print $1, $2, $3, $4, substr($5,1,8}

I tried using an awk gsub () command within the string instead of the two seds, but it did not work:
awk '{ print gsub(/<regex>/, <replace with>,$1), $2, $3, $4, substr($5,1,8}
the sed works ok, but it would be cooler to make the replacement within the awk command:
gsub(/->/,-> IN, $1)
Is there a way where i could replace the value of the $1 column in the awk print string?

I am doing a spreadsheet for work (for importing data into a new database) and I have hundreds of image files which need to have just their file names in one column called Product Code. Is it possible to use the ls command to list the contents of a directory in one single column so that I can copy and paste to the spread sheet?
Also, is there a single command to remove the file extentions for a batch of files? Bulk rename is what I need, I guess but just to remove the file extension (.jpg on all of them). The normal use of ls lists them in multiple column form and when I copy and paste those it will not let me copy just one cloumn at a time. The spreadsheet only has three columns:
New Product Code Old Product Code Pictures New Product Code will be left black, and the Old Product Code is just the image names. The picture column will be the patch-to-the-image for each image. I am not sure that is even possible in a spreadsheet.

Have this script which is reading in a series of files, one at a time with while-do-done loop, each file goes through various greps/awk's where this info is then saved to various files for later use. i.e....
Script is being run on Linux Red Hat,
In one of the grep/awk's the output (currently) are 2 columns (min max), i.e....| awk '{print $1, $2}' | sort -u which outputs (e.g.)
The number of "min max" pairs varies from file to file. Want to output a single column of unique numbers from the min max pairs & get the number of them for input to a file...i.e...
Where <PROCESS> is some process/technique that will generate a single column of integers (increment of 1) to pipe into the next one (sort -u)
i.e. (example from above)
Have tried command seq - only works for single pair input i.e.
Is there any command like seq etc which will output a single column based on a input of min max numbers (increment 1) to pipe onwards to next command?
Is there a way to get the "ls -l" command to align its columns (e.g. force a fixed size) when the command is executed individually for each file to be listed (e.g. in a script loop or such)? Right now, I get ragged/jagged columns because "ls -l" is trying to make each listing compact horizontally. But as file sizes, and lengths of owner names, and such vary, the overall length of each output instance varies, making the columns ragged.

Im trying to use awk to do matching in only a specific column
example.txt:
www.google.com www.example.com
www.google.com/search www.example2.com
i used:
awk '{ (if $1 == "http://www.google.com") print $2}' example.txt
this awk statement only returns the first line, and i cant seems to make it perform in a way to match based on keywords like GREP. Is there any way to make display the other lines which contains "google" also?

where the [] means space. This is not what i want. I guess that is because the OFS is one space by default, but i really don't know how to solve this.

I have a text file and I need to replace the 3rd column of that file from row 3 to the end of the file with a column which I have stored in the different text file. For e.g the original file is like given below:

2 0.6509 194.00 2.0316 -17.50 18.00 -3.00 0.6250 1613 4
3 1.0128 8.00 2.1457 -17.50 18.00 -3.00 0.6250 1616 1
4 1.3748 192.00 2.2598 -17.50 18.00 -3.00 0.6250 1616 4
5 1.6986 7.00 2.3619 -17.50 18.00 -3.00 0.6250 1616 1
6 1.9347 120.00 2.4364 -17.51 18.00 -3.00 0.6250 1616 5
7 2.1327 190.00 2.4988 -17.34 18.00 -3.00 0.6250 1616 4
So lets say I wanna replace column 3 from row 3 to row 7 with a data from another file which is given below:
54.00
239.00

52.00
165.00

So the final output file should be like this:

And I will post the code whatever i have tried soon. I started with awk and cut commands..but never got it to work and also tried PASTE command too.
What I need to do is to extract one complete column (file size) from the output of ls -lS but while doing so in some rows I have a single space but in some other rows I have 2 or 3 spaces like some file sizes are different with 30 bytes 400 bytes and some 4000 bytes. So when I extract the output of ls using | cut -d ' ' -f5 i get the value which has only one space i.e. I get 4000 as output because 400 has 2 spaces seperated and 30 is 3 spaces separated. So how to get the file size column from the ls output?
