Hi

sed 's/[^0-9]*//' file

Guru.

Are you aware that these stipulations will exclude a "linux-something" at the lines end from being removed because there will be no space afterwards? Maybe this is not what you want. Also notice that...

The previous sample matches and removes leading space.
It's also possible with trailing space. With portable perl one can even include TABs
perl -pe 's/linux-\S+\s+//g'Most exact is a "begin...

something along these lines:

sed 's/[ ][ ]*linux-[^ ][^ ]*//g' myFile

It looks like (even though we are not dealing with *nix text files due to missing <NL> char at the end) GNU sed could do it, not with octal constants, but with hex constants:
sed ':L;s/\000$//;tL'...

I misunderstood your requirements. Even though you said you wanted to remove trailing nulls, the way you said that you wanted to stop removing nulls when a different byte was found sounded like you...

You don't need random access for your output file. You'll just be doing sequential writes to your output file. You'll also just doing sequential reads from your input file (once you seek to the...

Why use java? This is a perfect problem for the dd utility.

OK. Show us the java code and show us where in the code you are running into buffering problems.

The code has everything to do with it.

Why do you believe that you have to copy everything into an array before you write any of your desired output?

Open your input file. Seek to the offset...

For a return from main(), the return code is equivalent to a call to exit() with that return code. And from the standards, the description of exit(status) is:


For a return from any other...

By convention in the standards:
0 success
1-125 a program specific failure
126 when trying to execute a command, a file was found with the
specified command name, but it was not executable...

The convert utility which is a part of imagemagick will do what you need. Basic command line is:


convert +append image1.jpg image2.jpg product.jpg


The two images are placed side by side;...

man stat and man strftime for more details.

stat -f "%Sm" -t "%Y%m%d%H%M.%S" FILE

If you really would need a ' within a ' ' string then you need to end the string with ' then follow an escaped ' then another ' to begin a second string.
echo "some text with spaces" | sh -c 'sed -e...

A bit of background: sh -c expects a single string, which is interpreted as a command. Anything after that are positional parameters to that command. So by this way of quoting, sh -c gets passed two...

Try
echo "some text with spaces" | sh -c 'sed -e "s/ //g"'
and/or
echo "some text with spaces" | sh -c 'sed -e 's/[[:blank:]]//g''
and/or
echo "some text with spaces" | sh -c "sed -e 's/ //g'"
...

The reason is that >aaa and >bbb are handled by the shell.
While it does not matter where you place them, one usually places them at the end.
So your code is identical to
find mydir -type f -exec...

Hi,

Try:
stat -c %G "$line"

One way:
find mydir -type f | tee -a aaa > bbb

You do not need echo, find prints by default.

1. The %Y format specifier in stat -c command gives the time output in unix time from epoch.
2. I tried the command on Terminal IDE app (BusyBox v1.19.2) installed on my android phone (running...

Here's one way to do it:
[user@host ~]$ date -d @$(stat -c%Y file) +"%Y%m%d%H%M%S"
20140118220547
[user@host ~]$

You combined file and file system stat queries, which does not work. And you gave a format descriptor without the -c or --printf option (on top of the fact that there's no date/time info for file...

Abrahao,

You can use rcp command instead to retain modification times access times and modes of the original file. (Use rcp -p)

If you want to change access/modification times use touch...

Hi Abrahao,

I think u can better tar the files , ftp it and untar it at the other end ... and the timestamp would be preserved ... try this way ... i guess this wud be better than changing the...
