Any of the two work, because the apt command uses space as argument separator, when there are one or more spaces at the end they are ignored and two or more spaces in any place are condensed into one.

I want to delete all matches in a text following this pattern:


Each match starts with linux-
Each match ends with a space
(Remove linux-* until immediate next space)

At the end of a binary file

No idea what can be the cause, but with large files it doesn't remove all the trailing null characters.

A file of 3239571456 bytes resulted in 2902450247 with dtn.c
The same file resulted in...

Thank you very much, it works perfectly.

That command removes all nulls. I need to remove only the ones that are at the end of the file just after the last non-null character, not in the middle of the file.

I want to remove from a file the trailing null characters (0x00) and stop doing so when a different byte is found (which should not be deleted), and either put the result to the same file or a...

My mistake. It's python, not perl. I wrote incorrectly the thread title.




It doesn't matter because we are passing by value, not by reference, which is what @Aia suggests (reading from...

I want to send the content of a bash variable as a python argument for processing. The problem is that bash doesn't "expand" the content, just sends the expression.

script.sh#!/bin/bash

So do you think RandomAccessFile will be the simplest way to achieve that? If I write byte by byte is may cause a lot of I/O overhead, specially bad for SSD drives. Writing in blocks of 1MB or so I...

I'm not sure I need to show internal code that has nothing to do with it. Basically I think the issue comes from the maximum number of items into a byte array. Say an example program already contains...

Because the software that detects the start and end offsets is entirely written in java, and I want it to be portable.

I need to save part of a file to a different one, start and end offset bytes are provided by two counters in long format. If the difference is big, how should I do it to prevent buffer overflow in...

And what about negative numbers? I've seen the return -1; quite often

The standard return code when everything goes right is 0, but what about using any other number something happened? Are there "ranges" depending on the kind of problem you want to express or is...

printf is not available on android, os x or freebsd so isn't really portable. I'll stick with the sed option.

When I specify a directory by name the leading ./ is not shown:
$ find somedir/
somedir/a.bin
somedir/target/out.binBut when I specify current dir it adds the ./ to the beginning of each result:...

This example shows last mtime from epoch
$ stat -f %m somefile
752911565

But would like to see it like that:

The following command works echo "some text with spaces" | sh -c 'sed -e 's/t//g''But this doesn't and should echo "some text with spaces" | sh -c 'sed -e 's/ //g''Any ideas?

Thanks worked!

Example:
while read line
do
stat -c %G $line
done < somefile.txtThe problem is that inside somefile.txt lines can have any symbol allowed as file name, like (). Even with spaces, it splits the...

Example script:

find mydir -type f -exec echo {}>aaa \; -exec echo {}>bbb \;The two paths go the the bbb file, while there should be one of them on each file. How should I do it to get it working?

$ date -d @$(stat -c%Y file) +"%Y%m%d%H%M%S"
unknown option -- ddate: invalid option -d

This example works perfectly on Cygwin, however it doesn't on android, where timestamps are always read and written in unix time from epoch.

Need help reading file last modified date in format:

Filename (relative path);YYYYMMDDHHMMSS

And then write it back. My idea is to backup it to a text file to restore later.
