- 一，将SVN版本信息添加到我们的程序版本中
-
- 1，使用sed命令修改源代码/Makefile中的版本号，添加SVN版本信息：
-
- #!/bin/sh
- #File Name: build-l200.sh
-
- #Get the SVN version number
- svn_ver=`svn up|grep revision|awk -F' ' '{ print $3 }'|awk -F'.' '{print $1}'`
- echo "SVN Version: $svn_ver"
-
- #Find the Version line
- line=`sed -n '/#define DROPBEAR_VERSION/=' options.h`
-
- #Instead the original version by mine
- sed -i -e ${line}s"/.*/#define DROPBEAR_VERSION \"0.51 Build ${svn_ver}\"/" options.h
-
- #compile the source code
- make
-
- 2， 将SVN版本信息放入version.h头文件中，在源代码中在包含该头文件并引用他们：
- a, makefile中定义版本信息并调用scripts/mkversion脚本:
- CROSS_COMPILE =
- ARCH= L200
-
- MAJOR=1
- MINOR=0
- REVER=0
- SVNUP=1
-
- all: entry version at
- version:
- @echo " ";
- @echo " =========================================";
- @echo " ** Create Software Version Head File **";
- @echo " =========================================";
- sh scripts/mkversion ${SVNUP} ${MAJOR} ${MINOR} ${REVER}
-
- b, scripts/mkversion脚本：
-
- #!/bin/sh
-
- GET_SVN=$1
- MAJOR=$2
- MINOR=$3
- REVER=$4
-
- if [ $GET_SVN -eq 0 ]
- then
- echo "============ Skip svn update ============"
- exit;
- else
- echo "============ SVN update and get svn version now ============"
- svn up
- svn_ver=`svn up|grep revision|awk -F' ' '{ print $3 }'|awk -F'.' '{print $1}'`
-
- echo "/* This is generate by makefile , don't Edit it by hand */" > version.h
- echo "#define MAJOR ${MAJOR}" >>version.h
- echo "#define MINOR ${MINOR}" >>version.h
- echo "#define REVER ${REVER}" >>version.h
-
- if [ ! -z $svn_ver ]
- then
- echo "#define SVNVER $svn_ver" >>version.h
- else
- echo "#define SVNVER 0000" >>version.h
- fi
- fi
-
- 3, 使用sed修改Makefile文件： 替换行/行前插入/行后插入
-
- 例一：
- FILE=src/pkcs11/Makefile
-
- #将文件中所有的$KEY替换成$INSTEAD
- KEY="-module -shared -avoid-version -no-undefined"
- INSTEAD="-module -static -avoid-version -no-undefined"
- sed -i -e "s/${KEY}/$INSTEAD/g" $FILE
-
- #找到某一行，并在其后插入一些行；
- FILE=src/libopensc/Makefile
- line=`sed -n '/all: all-am/=' $FILE`
- #替换该行内容
- sed -i -e ${line}s"/.*/all: all-am L200_rebuildLib/" $FILE
- #在该行后插入一些新的行
- sed -i -e `expr $line + 1`a"L200_rebuildLib:" $FILE
- sed -i -e `expr $line + 2`a"\\\tcp \`dirname \${abs_top_srcdir}\`/pcsc-lite-1.5.5/src/.libs/libpcscl
- ite.a \${abs_srcdir}/.libs" $FILE
- sed -i -e `expr $line + 3`a"\\\tsh \${abs_srcdir}/L200_rebuildLib.sh \${abs_srcdir}\n" $FILE
-
- 找到某一行，在该行前插入一行:
- FILE=src/Makefile
- #找到要修改的行号
- line=`sed -n '/CFLAGS = -Wall -fno-common/=' $FILE`
- #替换该行的内容
- sed -i -e ${line}s"/.*/CFLAGS = -Wall -fno-common -O2 -Wl,-elf2flt='-s 262144'/" $FILE
- #在该行前插入一行注释
- sed -i -e ${line}i"# Set stack size as 256K" $FILE
-
- 找到某一行，删除该行第一个字符:
- KEY="#am__EXEEXT_1 = cryptoflex-tool"
- line=`sed -n "/$KEY/=" $FILE`
-
- if [ $line ] ; then #如果变量不为空，即找到该行
- sed -i -e "${line}s/.//1" $FILE #这里的1即为第一个字符，若修改第二个字符则改为2
- sed -i -e "`expr $line + 1`s/.//1" $FILE
- sed -i -e "`expr $line + 2`s/.//1" $FILE
- fi
-
- 例二：
- CROSS=/opt/buildroot_350/build_arm/staging_dir/bin/arm-linux-uclibc-
- # | -----------------------------
- # | Cross compile iproute2-2.6.34
- # | -----------------------------
-
- if [ ! -d iproute2-2.6.34 ] ; then
- tar -xjf iproute2-2.6.34.tar.bz2
- fi
-
- if [ -d iproute2-2.6.34 ]; then
- cd iproute2-2.6.34
- FILE=Makefile
- sed -i -e 38s"/.*/SUBDIRS=lib tc/" $FILE
-
- line=`sed -n '/^CC = gcc$/=' $FILE`
- if [ $line ]; then
- sed -i -e ${line}s"@.*@CROSS=$CROSS@" $FILE //由于$CROSS中中包含sed默认分隔符"\",所以我们这里改用@作为分隔符
- sed -i -e `expr $line + 0`a"CC = \${CROSS}gcc" $FILE
- sed -i -e `expr $line + 1`a"AR=\${CROSS}ar" $FILE
- sed -i -e `expr $line + 2`a"AS=\${CROSS}as" $FILE
- sed -i -e `expr $line + 3`a"LD=\${CROSS}ld" $FILE
- sed -i -e `expr $line + 4`a"RANLIB=\${CROSS}ranlib" $FILE
- fi
-
- make && cd -
- fi
-
- # | -----------------------------
- # | Cross compile redir-2.2.1
- # | -----------------------------
-
- if [ ! -d redir-2.2.1 ] ; then
- tar -xzf redir-2.2.1.tar.gz
- fi
-
- if [ -d redir-2.2.1 ]; then
- cd redir-2.2.1
- FILE=Makefile
- sed -i -e s":^CC = gcc$:CC = ${CROSS}gcc:" $FILE //这里选用":"作为sed 分隔符
- make && cd -
- fi
-
-
- 二，一些常用的alias:
-
- alias vt100='export TERM=vt100'
- alias linux='export TERM=linux'
- alias maek='make'
- alias rmsvn='find -name .svn -exec rm -rf {} \;'
- alias rmgdb='find -iname "*.gdb" -exec rm -rf {} \;'
- alias rmdep='find -name .depend -exec rm -rf {} \;'
- alias myindent='indent -npro -kr -bl -nce -bli0 -i2 -ts2 -sob -l80 -nfc1 -ss -ncs'
- alias myctages='ctags --c-kinds=+defglmnstuvx --langmap=c:.c.h.ho.hem.het.hec.hev.him.hit.hic.hiv -R .'
-
- alias nocvim='mv ~/.vimrc ~/.vimrcb'
- alias cvim='mv ~/.vimrcb ~/.vimrc'
- alias mntwinxp='sudo mount -t cifs -o username="username",password="password" //Winxp_ipaddr/linux /home/username/winxp/'
-
-
-
- 用于在文件中查找的脚本：
- #!/bin/sh
- # Description: This shell script used to grep the "key" in all the files
- find -iname "*$suffix" | xargs grep "$key"
- find -iname "*$suffix" | xargs grep "\<$key\>"
- # in current folder.
- # Author: guowenxue(guowenxue@gmail.com)
- # Version: 1.0.0 (Release by guowenxue on 04th Feb. 2010)
- # ChangeLog: None
- #
-
- if [ $# -lt 1 ] ; then
- echo " Usage: $0 key [-g] [suffix]"
- echo "Example1: mygrep haha"
- echo "Example2: mygrep haha -g"
- echo "Example1: mygrep haha *.c"
- echo "Example1: mygrep haha -g *.c"
- exit;
- fi
-
- key=$1 #The grep key
-
- if [ $# = 1 ] ; then
- grep -n "$key" -r *
- elif [ $# = 2 ] ; then
- if [ $2 = "-g" ] ; then
- grep -n "\<$key\>" -r *
- else
- suffix=$2
- find -iname "$suffix" | xargs grep -n "$key"
- fi
- else # Arguments more than 3
- if [ $2 = "-g" ] ; then
- suffix=$3
-
- elif [ $3 = "-g" ]; then
- suffix=$2
- fi
-
- find -iname "$suffix" | xargs grep -n "\<$key\>"
- fi
-
-
- [guowenxue@localhost drivers]$ mygrep 15000400
- csps/lpc313x/include/lpc313x_chip.h:#define LCD_INTERFACE_BASE 0x15000400
- [guowenxue@localhost drivers]$ mygrep 15000400 .h
- ./csps/lpc313x/include/lpc313x_chip.h:#define LCD_INTERFACE_BASE 0x15000400
- [guowenxue@localhost drivers]$ mygrep 15000400 .h -g
- [guowenxue@localhost drivers]$ mygrep 15000400 -g .h
-
- Sed命令去掉补丁文件中首字符"+",获取C代码文件：
- [guowenxue@localhost spi]$ sed -i 's/^+//' tsc2046.h
-
-
- 清除所有ARP缓存表：
- for ip in `seq 1 6`; do arp -d 192.168.5.$ip; done
