  1. Windows Batch VS Linux Shell Jason Zhu

  2. Agenda • System and Shell • Windows batch and Linux Shell • Dos and Linux Shell internal Commands • Windows and Linux external commands • Batch and Shell variable and special sign • Batch and Shell Key words • build forge VS batch/shell • Batch/Shell VS Perl/python

  3. System history

  4. Shell history • Shell: a piece of software that provides an interface for users • Unix/Linux: Bourne/Korn/C/Tc/Bash • Linux GUI: Gnome,kde,xfce • Windows: cmd.exe/explorer.exe • http://en.wikipedia.org/wiki/Shell_(computing)

  5. The difference of Windows and Linux • Case sensitive in Linux • / in Linux • No relationship between executable file and extension • don't search current path • Security policy is more strict in Linux • link file VS shortcut • http://en.wikipedia.org/wiki/Comparison_of_Windows_and_Linux

  6. Same internal commands

  7. Different internal commands

  8. Other internal Commands

  9. Command help

  10. External commands

  11. Where to get more useful tools • http://unxutils.sourceforge.net/ • ftp://ftp.microsoft.com/reskit/ • http://www.microsoft.com/mspress/windowsserver2003reskit/ • http://live.sysinternals.com/ • http://www.nirsoft.net • Other such as zip/unzip…

  12. Robocopy(windows) • windows copy/xcopy: • copy “c:\new folder\1.txt” c: • copy “c:\new folder\1.txt” c:\2.txt • Linux cp/windows cp.exe • cp ~/a.txt ~/test (cp c:\1.txt c:\test2) • cp ~/a.txt ~/test/b.txt (cp c:\1.txt c:\3.txt) • Windows robocopy: • robocopy /E /NP /R:12 /w:10 /MIR SourceDirDestinationDir *.txt *.doc /XF test.txt /xd test • Must check the return value

  13. Printf(windows/Linux) • Printf • Printf %3d 2 • printf %-3d 2 • Printf %03d 2 • Printf %1.2f 3.1415926 • printf %8s "aaaa" • printf "\nSubDoc: %03d\n" 3

  14. Expr(windows/Linux) • expr 5 + 7 expr 5 – 6 • expr 5 ”*” 4 expr 5 / 7 • expr 7 % 9 • expr 1 “|”   0 expr 1 “&” 0 • expr 3 “>” 6 expr 3 “<” 6 • expr 3 “>=” 3 expr 3 “<=” 3 • expr 3 = 3 expr 3 != 3 • exprexpr1 :re expr index expr1expr2 • exprsubstrexpr1expr2expr3 • expr length "abcdef" • expr length "abcdef" "<" 5 "|" 15 - 4 ">" 8

  15. Awk(windows/Linux) • awk '{print $0}' scores.txt • awk '{if($2 ^> "60") print $0}' scores.txt • awk 'BEGIN {print "start..."} {tot+=$2} END {print "totoal is:" tot; print "END..."}' scores.txt • awk '{print length($2)}' scores.txt

  16. sed • sed [选项] s e d命令 输入文件。 • sed = test3.txt • sed s/mapguide/mapguide2010/g test3.txt • sed 5,6d test3.txt • sed 3a\abcd test3.txt • sed 10i\adflajflad\n\adfadfajdlf test3.txt • Sed 10c\aaaa test3.txt • sed 4q test3.txt • sed 2r 1.txt test3.txt

  17. grep • grep "map" test4.txt • grep "map" *.txt • grep -c “aud“ test4.txt • grep -n “aud“ test4.txt • grep -v “aud“ test4.txt • grep -i “aud“ test4.txt

  18. Batch VS Shell

  19. Environment variables

  20. Environment variables shift

  21. Environment variables

  22. Linux 参数变量 • a. 变量=${参数-word}：如果设置了参数，则用参数的值置换变量的值，否则用word置换。即这种变量的值等于某一个参数的值，如果该参数没有设置，则变量就等于word的值。 • b. 变量=${参数=word}：如果设置了参数，则用参数的值置换变量的值，否则把变量设置成word，然后再用word替换参数的值。注意，位置参数不能用于这种方式，因为在Shell程序中不能为位置参数赋值。 • c. 变量=${参数？word}：如果设置了参数，则用参数的值置换变量的值，否则就显示word并从Shell中退出，如果省略了word，则显示标准信息。这种变量要求一定等于某一个参数的值。如果该参数没有设置，就显示一个信息，然后退出，因此这种方式常用于出错指示。 • d. 变量=${参数+word}：如果设置了参数，则用word置换变量，否则不进行置换。

  23. Call/start/source/sh

  24. Special signs

  25. Expression caculation

  26. Error status

  27. 变量延迟 If/then/else

  28. Label/goto/function

  29. For

  30. Linux- Until/while/case/break/continue • while CONTROL-COMMAND; do CONSEQUENT-COMMANDS; done • until TEST-COMMAND; do CONSEQUENT-COMMANDS; done • case EXPRESSION in CASE1) COMMAND-LIST;; CASE2) COMMAND-LIST;; ... CASEN) COMMAND-LIST;; esac • select WORD [in LIST]; do RESPECTIVE-COMMANDS; done • Break/continue

  31. Build Forge vs batch and shell • variables definition : build forge syntax • Variables using: both of windows and Linux • Slashes: both of them are ok • For linux OS: shell syntax • For Windows OS: batch syntax

  32. Batch and shell VS perl and python • Shell simply and suitable for daily work • Perl/python can work in different os; more powerful; but complex;

  33. Shell and batch references • http://technet.microsoft.com/zh-cn/library/cc758944(WS.10).aspx • http://www.arachnoid.com/linux/shell_programming.html • http://www.freeos.com/guides/lsst/ • http://linuxcommand.org/
