Hi all, As i know bash shell should be most popular on linux. But , which shell popular on Unix... Such as on Solaris and freebsd... As i use freebsd for my hobby and Solaris for job, i want to learn to write shell scripts on both OS, it is not easy for me to choose which shell is better for both OS. i have found that on Solaris, the people like choose ksh to work with shell scripts, on Freebs...

I do not know which place the script run for example function a { } function b { } function c { } #point b a c i think the first script which being run is from '#point', i mean that b is first to execute think you

过程如下： （gcc是在redhat的源代码光盘中找到的。） [root@rxy root]# rpm -ihv gcc-3.2.3-20.src.rpm warning: gcc-3.2.3-20.src.rpm: V3 DSA signature: NOKEY, key ID db42a60e 1:gcc ########################################### [100%] [root@rxy root]# which gcc /usr/bin/which: no gcc in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin) 请教各位师兄！到底gcc安装到哪里去了呢...

hi, there: It may seem irrelevant, but does anyone know or used gcc compiler in a shell script? I need to use gcc to compile a c file and change a variable in the file by setting a parameter of gcc (-D :?: ). If this works, gcc will generate an executable file with the name of that parameter (variable). That is it. I hope I made myself clear enough. Thanks in advance!

:em10: 各位大侠好：）首先谢谢先！我想在armlinux下作ppp拨号的开发？请教一下前辈，想找到些指点：）

我查了我机子的usr/bin 和bin，但没有发现perl，是不是说明我的机子没有安装perl，不能进行perl开发.另外我的一本参考书上说用which perl命令可以找到perl的路径,但我运行后提示which --not found，倒底有没有which这个命令.

小弟前一阵子参考资料移植了一个armlinux到我的板子上，芯片是ep7312。利用设备驱动程序原理做了一个走马灯的应用程序加到romfs的文件系统下，启动之后也能正常运行。接下来就希望利用fiq实现linux下的快速中断，结果就出现了这样的异常： Bad mode in data abort handler detected: mode FIQ_32 Vectors: Stubs: Internal error: Oops: 0 CPU: 0 pc : [] lr : [] Not tainted sp : c0e83c30 ip : c0e8...

freebsd72# which nologin /sbin/nologin freebsd72# whereis nologin nologin: /usr/sbin/nologin /usr/share/man/man8/nologin.8.gz /usr/src/usr.sbin/nologin nologin命令实际上在/usr/sbin/目录。 我的问题是 为什么which会返回这样的结果？这个结果是错误的。 如何修正这个错误？

用smitty hacmp或 smitty cl_convg创建了并发卷组，major number都一样，用于磁盘心跳，没有创建任何逻辑卷；创建后用smitty hacmp使用List All Concurrent Volume Groups on the Cluster 显示 cl_lsvg: no volume groups found 有人遇到过这个问题么？用磁盘做心跳需要什么条件；目前的情况使用的是tmssa做的heartbeat

which "${0##*/}" 中的 "${0##*/}"是什么意思呀
