从报错信息来看,cat的文件是一个二进制文件,不能直接grep 查找条件进行查找,需要修改为grep -a 查找命令。 有几个点需要解决: 1.什么是二进制文件? 2.为什么二进制文件不能直接grep 查找条件? 3.-a具体指的是什么?解决哪些问题?

The results shown indicate that this word was found in “textfile.txt,” and there are matches for this word in “WXP-PRO-OEM.iso” also. Because this is a binary file, further techniques will need to be used to make the content viewable. kstrzempka@linux-wks-001:~/Desktop$ grep ...
R Repaint the screen, discarding any buffered input. Useful if the file is changing while it is being viewed. F Scroll forward, and keep trying to read when the end of file is reached. Normally this command would be used when already at the end ...
By default, if decompressing into a regular file, xz tries to make the file sparse if the decompressed data contains long sequences of binary zeros. It also works when writing to standard output as long as standard output is connected to a regular file and certain additional conditions are ...
This can be done using one of the three options below: CONFIG_OF_EMBED If this variable is defined, U-Boot will embed a device tree binary in its image. This device tree file should be in the board directory and called <soc>-<board>.dts. The binary file is then picked up in board...
Browser, Virtual Machine, and Kernel all play an important role in binary security. And I decide to study browser first. I choose a relatively easy one: WebKit. (ChakraCore might be easier, LoL. But there’s a rumor about Microsoft canceling the project. Thus I decided not to choose it...
