File operations
Remove files
Sometimes a file starts with a dash (-), for example, you ended up with a file named "-help". (don't ask me how you did it...) Of course you can remove the higher directory, but there are other ways of removing this file:
rm -- -help rm ./-help
Change files
Change the serial of a zone file. This is for BSD.
sed -i '' 's/2020022301/2020022302/g' filename
Extract files
Extract all files out of an image.
binwalk --dd='.*' file.bin
Mount ISO partitions
This is a raspberry pi image:
user@wks010~/Download$ sudo parted disk.bin unit s print Model: (file) Disk /home/user/Download/disk.bin: 581632s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 8192s 49151s 40960s primary fat16 boot, lba 2 57344s 581631s 524288s primary ext2
To calculate the offset, its in this case the start value times 512, so 8192 * 512 = 4194304
user@wks010~/Download$ sudo mount -o loop,offset=4194304 /home/user/Download/disk.iso /mnt/mydisk
List operations
Sort IP adresses
Sort a list of IP adresses.
sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4
Thanks: https://www.madboa.com/geek/sort-addr/
Processes
Kill processes
Kill your current process.
kill -9 $$
Networking operations
Scan PTR records
Do a reverse scan of an IP range.
