Can we find the inode of a particular file using its inode number?
The reason is i want to know how many blocks are occupied by specific file.
if we consider block size of 1K.
if the file size is of 100 bytes. In such a case, when the file is
stored on disk, the file will occupy 100 bytes or 1K (since we have
choosen block size to be 1K) ?
If you create a file on UNIX/linux with special chars, like touch "la*, you can't remove it with rm "la*. You have to use the inode number(you can if you add the before the name, I know, but you'd have to guess as a user that it was used in the file creation).
I checked the manpage for rm, but there's no metion of the inode number. Doing rm inodenumber doesn't work either.
What is the command for this?
How can i recover a file if i don't know the inode number of it? Is there a way of scanning the hard drive for inodes that has no reference?

In the AM I get yelled at by users. all it takes is an fsck to fix the problem, but it does it every night. I have tried to rebuild the journal by removing the has_journal flag, running an fsck, and then re-adding the journal... same problem.. and its always the same inode.

I'm looking for a way to insert the number of lines in a file to the start of the aformentioned file. This should be simple but as I am not used to scripts in Linux, I am finding it tough going. I can find the number of lines in a file easily enough via
filesize=$(awk 'END {print NR}' $1)
but as for inserting this into the first line, i'm failing to do so. I've tried some of the other approaches on these forums but none so far have been able to do so.
I've tried:
sed '1i$filesize' $1
but sed i requires a string, not a variable so no go I've also tried:
mv "$1" "${1}.bak" 2>/dev/null || touch "${1}.bak"
cat $filesize "${1}.bak" >"$1"
but again with no luck as cat seems to need an input stream Just to recap, i want to insert a line at the start of a given file that holds the number of lines the original file has.
ie the file:
a
b
c
d
e
should become:
5
a
b
c

I need to get the max number from the name of a file
Formant of the file name:

Delimiter as underscore '_'
[code]....
known part in the above file name will be GA.log A give directory may or may not contain files in the above format or may contain file other then the above format if so then ignore it.
Eg:-
1) Directory=/tmp/log having below listed files
ant_01_EG.log ant_02_GA.log ant_04_EG.log cvs_01_EG.log cvs_02_GA.log cvs_04_EG.log master_01_GA.log master_03_EG.log master_04_GA.log
[code]....
output=> 06
2) Directory=/tmp/log no files
cmd=> ls *[0-9][0-9]_GA.log 2> /dev/null | awk -F_ '{ print $2}' | sort -nr | head -n1 | awk 'BEGIN { if ($1 >0 ) x=0; else x=1 } END {printf "%02.0f
", $1+1}'
output=> 01
if there are no files the output should be 01 and if file(s) found the output should be next highest number+1, In the above example it is 06 My cmd is bit lenghty. reduce my cmd and it should be in one line.

I'm currently trying to design a small, simple enough shell program for area codes. I have a list of area codes in a database, and I am trying to write a program that will have a user input an area code, and then have the program print out information that immediately follows that area code in my database. I assume I need to use a find or locate command, but I'm not sure if I should be searching for a string or the number itself. The number could possibly occur at some other point in the file, though the way I have the file set up it only occurs once at the newline.
what function I should use and how I should go about it? As is I only have the absolute bare-bones beginning of having an echo for the prompt to input an area-code, and the read once it's input. Without the find I'm not sure how much farther I can get. Also, would it make it easier if I added some character such as a ! to the end of the number at the newline to make it easier to search for? With a macro that would be easy enough to do.
I'm trying to write a script that takes two arguments, the first argument is a number, and the second argument is a filename. The shell script should indicate if the file's size is BIGGER or SMALLER the number provided. this is what i have sofar, am i on the write track, i'm hoping its just a problem with my if command
if [ $1 -h $2 ]
then
echo "$1 is bigger than $2"
