Hi friends
I'm newbie here, at first, I wanna to say "Hi, so nice to be here" to all you.
I've got a problem in my work and need your help, thx in advance

I have to write a shell script to create one or many bigfiles (>1Gb). I was able to do that by using some nested big-while-loop, echo "", ">", ">>" character to put texts into a file, but It's apparently a stupid way.

Experts, please be kindly help me. Is there any other way to create a big-file? the data stored in the file is anything!

Many thanks

Why Don't you use seq command to create the File. use man seq for others parameters.

Don't really understand so please forgive me if this crass.

Create a file with $ touch filename. Glue the first file to the second with: $ cat file1 >> file2. $ dd if=/dev/zero of=filename bs=1024 count=1000000 gives a 1GB file full of zeros.

Thx friends, I tried as your suggestions
Using $dd is the good and quick way to create a big-file, but not sure what happened! lugoteehalt, could you please help me to make it clear?

I used file1.txt (included text "Hello, so nice to meet you") instead of /dev/zero, and not able to create a 1 GB file

Quite clear now by means of wiki . But I'm still a little bit confused, How could I create a 1-GB-file included non-null character
Many thanks

I'm not really an experienced scribe. Perhaps something like string together a load of Hello, nice to see you's to make 1KB - you could do this easilly with vim, say - this step isn't really necessary then:

for n in 1000000 this work??
cat file >> bigfile
