Commands on Commands
Hi all,
I am in need of commands which are capable on running on commands I know these below commands as of now, please share your thoughts strace -- very much handy when debugging a command/script which will struck in middle of execution. This command will be tough when you start using it initially, but will come hand when start using excessively. and there are some more sister commands for this ie ltrace mtrace which i never used, please give some inputs on these... For example if we want to see how ls command is executed and what to see what actually ls command is doing.. you can check that out by using strace Code:
strace ls some valuable examples 1)monitoring a copy activity of CD/DVD, which will show the progress. Code:
cp -ar /dev/cdrom /mnt & watch ls -l /mnt Code:
watch lsof -i Code:
time ls time shellscript.sh Code:
whereis ls Code:
whatis ls Code:
man ls info ls

gdb is used to debug programs or servers which are crashing or chrooted servers. This is also useful to debug various apps which works everywhere but not on your server for some weird causes. Most Linux server comes as open source project hence it is possible to use gdb. However, it is more of programmers tools.

 'gdb' can also used be used in Linux servers to analyse the 'core' files created. This is a good link to learn how to use it - How to analyze a core file and submit information to support
