http://www.unix.com – Hi, I am thinking to increase my knowledge towards shell scripting and tcl scripting. The thing is, please suggest me a script which i can code is useful in learning as well as to project it to my team mates and it is helpful to all my office team mates. I'll give you an idea of what we regularly use in my office. 1. fix bugs in tcl and shell 2. daily we runinit eval boards (initialization which runs for min 25mins) 3. we use vim, nedit, gvim, cscope, clear case. Please suggest me something which will be useful to all. Any general script is also fine. Thanks in advance (HowTos)
