Create a large text file with shellscript

Create a large text file with shellscript

I needed a text file of the specified size for testing, so I checked the command to create.

1MB text file

cat /dev/urandom | base64 | head -c 1000000

If this is the case, it will be one line, so I want to insert a line break.

1MB text file (with line breaks)

Create a 1MB text file and start a new line by 10 lines.

cat /dev/urandom | base64 | head -c 1000000 | fold -10

For binary files

1MB binary file (mac)

mkfile 1m dummy

1MB binary file (linux)

dd if=/dev/zero of=test bs=1024 count=1024
