很方便的两个shell script

最近我把系统重作了一下，于是成了 WIN98 和 linux 共存的系统， 但工作久了，发现很不方便（在 WIN98 下的文件名都是大写，而 linux 下的文件名一般都是小写字符）。在使用 mcopy 的时候，拷过来的文件名都是大写的，很不方便 linux 操作！
于是就写了两个shell脚本，这几天我用它们方便了许多操作，现在拿出来给双系统的朋友分享（我知道，像我这样用双系统的人很多哟！ ;-) ），应该有人能用上它。 脚本很简单，不过在发此贴之前把它们包装了一下（这样看起来就像个系统命令了，呵呵）。不足的是，只能改当前的目录中的文件名（就是说，只可以：% upks2lowks * 或 % upks2lowks myfile, 而不能 % upks2lowks /mydir/myfile），其实后者也可以，不过会有错信息输出！
脚本内容如下：
#!/bin/sh
# This Shell Script can change UPPER-CASE FILENAME to low-case filename.
error=0;count=0
number=$(echo * | /usr/bin/wc -w)
if [ "$1" = "-h" -o "$1" = "--help" ]; then
echo "Usage: upks2lowks [PATH] [FILENAME]..."
echo "Description: Change "FILENAME" to "filename"!"
echo ""
echo " -h, --help display this info and exit"
echo " -v, --version display version info and exit"
echo ""
echo "Report bugs to <[email protected]>."
echo "PS: I think U can modify it by nothing! It's just a shell script! ;-)"
exit
fi
if [ "$1" = "-v" -o "$1" = "--version" ];then
echo "A tool form my file-utils, no version info!"
echo "(maybe ver0.0.0)?! (^o^)"
echo "Written by Juner.L"
echo ""
echo "Copyright (C) Juner"
echo "This is free software; see the source for copying conditions. There is NO"
echo "warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE."
exit
fi
if [ -z "$1" ]; then
/usr/bin/printf "a"
echo "Just put the "FILENAME" follow the command!"
else
for i in $*
do
if [ -e "$i" -a -w "$i" ]; then
file=$(echo $i | /usr/bin/tr "[A-Z]" "[a-z]")
if [ "$i" = "$file" ]; then
echo "The file "$i" is already lowcased!"
count=$(/usr/bin/expr 1 + $count)
else
echo "$i => $file"
/bin/mv -f $i $file 2> /dev/null
fi
else
echo "warning: file "$i" not exist OR you have no "w" right to file!"
fi
done
if [ "$number" -eq "$count" ]; then
echo " all file(s) is lowcased!"
else
echo " $count file(s) already lowcased!"
fi
fi
还有一个和它差不多，只改了几个小地方，是把小写的文件名改成大写的，如下：
#!/bin/sh
# This Shell Script can change low-case filename to UPPER-CASE filename.
error=0;count=0
number=$(echo * | /usr/bin/wc -w)
if [ "$1" = "-h" -o "$1" = "--help" ]; then
echo "Usage: lowks2upks [path] [filename]..."
echo "Description: Change "filename" to "FILENAME"!"
echo ""
echo " -h, --help display this info and exit"
echo " -v, --version display version info and exit"
echo ""
echo "Report bugs to <[email protected]>."
echo "PS: I think U can modify it by nothing! It's just a shell script! ;-)"
exit
fi
if [ "$1" = "-v" -o "$1" = "--version" ];then
echo "A tool form my file-utils, no version info!"
echo "(maybe ver0.0.0)?! (^o^)"
echo "Written by Juner.L"
echo ""
echo "Copyright (C) Juner"
echo "This is free software; see the source for copying conditions. There is NO"
echo "warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE."
exit
fi
if [ -z "$1" ]; then
/usr/bin/printf "a"
echo "Just put the "filename" follow the command!"
else
for i in $*
do
if [ -e "$i" -a -w "$i" ]; then
file=$(echo $i | /usr/bin/tr "[a-z]" "[A-Z]")
if [ "$i" = "$file" ]; then
echo "THE FILE "$i" IS ALREADY UPPERCASED!"
count=$(/usr/bin/expr 1 + $count)
else
echo "$i => $file"
/bin/mv -f $i $file 2> /dev/null
fi
else
echo "WARING: FILE "$i" NOT EXIST or YOU HAVE NO "w" RIGHT TO FILE!"
fi
done
if [ "$number" -eq "$count" ]; then
echo " ALL FILE(S) IS UPPERCASED!"
else
echo " $count FILE(S) ALREADY UPPERCASED!"
fi
fi
完了！
经过进一步了解 gawk ，我已经把上面两个脚本优化了，改过后的脚本可以在任意目录下改任意目录（你有写权限的目录/文件）下的文件名，
也就是说，可以在任意目录下
% upks2lowks /home/juner/tmp/*
而不必
% cd /home/juner/tmp/
% upks2lowks *
改后的 shell script 如下：
（如果命令路径和你机器上的不一样，改成一样的就行了）
--------------------------------------
#!/bin/sh
# This Shell Script can change UPPER-CASE filename to low-case filename.
# init the vars!
error=0;count=0
number=$(echo $* | /usr/bin/wc -w)
# end of the "init the vars"!
# process the parameter(s)!
if [ "$1" = "-h" -o "$1" = "--help" ]; then
echo "Usage: $0 [PATH] [FILENAME]..."
echo "Description: Change "FILENAME" to "filename"!"
echo ""
echo " -h, --help display this info and exit"
echo " -v, --version display version info and exit"
echo ""
echo "Report bugs to <[email protected]>."
echo "PS: I think U can modify it by nothing! It's just a shell script! ;-)"
exit 0
fi
if [ "$1" = "-v" -o "$1" = "--version" ];then
echo "upks2lowks (a tool form my file-utils) ver0.1a"
echo "Written by Juner.L"
echo ""
echo "Copyright (C) Juner"
echo "This is free software; see the source for copying conditions. There is NO"
echo "warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE."
exit 0
fi
# end of the "process the parameter(s)"!
# working part!
if [ -z "$1" ]; then
/usr/bin/printf "a"
echo "Just put the "FILENAME" follow the command!"
else
for i in $*
do
declare -x filez=$(echo $i | /bin/awk BEGIN'{FS="/"} {print $NF}')
pathz=$(echo $i | /bin/awk BEGIN'{FS=ENVIRON["filez"]} {print $1}')
if [ -e "$i" -a -w "$i" ]; then
file=$(echo $filez | /usr/bin/tr "[A-Z]" "[a-z]")
#不好意思，刚发帖的时候直接把上面的粘贴过来，把 "$i" 改成 "$filez" 给忽略了，我现在改过来（不过下边的那个没错）
if [ "$filez" = "$file" ]; then
echo "The file "$i" is already lowcased!"
count=$(/usr/bin/expr 1 + $count)
else
echo "$pathz$filez => $pathz$file"
/bin/mv -f $pathz$filez $pathz$file 2> /dev/null
fi
else
echo "warning: file "$i" not exist OR you have no "w" right to file!"
fi
done
if [ "$number" -eq "$count" ]; then
echo " all file(s) is lowcased!"
else
echo " $count file(s) already lowcased!"
fi
fi
# end of the "working part"!
--------------------------------------
另一个文件也是这么改，道理是一样的。
--------------------------------------
#!/bin/sh
# This Shell Script can change low-case filename to UPPER-CASE filename.
# init the vars!
error=0;count=0
number=$(echo $* | /usr/bin/wc -w)
# end of the "init the vars"!
# process the parameter(s)!
if [ "$1" = "-h" -o "$1" = "--help" ]; then
echo "Usage: $0 [path] [filename]..."
echo "Description: Change "filename" to "FILENAME"!"
echo ""
echo " -h, --help display this info and exit"
echo " -v, --version display version info and exit"
echo ""
echo "Report bugs to <[email protected]>."
echo "PS: I think U can modify it by nothing! It's just a shell script! ;-)"
exit 0
fi
if [ "$1" = "-v" -o "$1" = "--version" ];then
echo "lowks2upks (a tool form my file-utils) ver0.1a"
echo "Written by Juner.L"
echo ""
echo "Copyright (C) Juner"
echo "This is free software; see the source for copying conditions. There is NO"
echo "warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE."
exit 0
fi
# end of the "process the parameter(s)"!
# working part!
if [ -z "$1" ]; then
/usr/bin/printf "a"
echo "Just put the "filename" follow the command!"
else
for i in $*
do
declare -x filez=$(echo $i | /bin/awk BEGIN'{FS="/"} {print $NF}')
pathz=$(echo $i | /bin/awk BEGIN'{FS=ENVIRON["filez"]} {print $1}')
if [ -e "$i" -a -w "$i" ]; then
file=$(echo $filez | /usr/bin/tr "[a-z]" "[A-Z]")
if [ "$filez" = "$file" ]; then
echo "THE FILE "$i" IS ALREADY UPPERCASED!"
count=$(/usr/bin/expr 1 + $count)
else
echo "$pathz$filez => $pathz$file"
/bin/mv -f $pathz$filez $pathz$file 2> /dev/null
fi
else
echo "WARING: FILE "$i" NOT EXIST or YOU HAVE NO "w" RIGHT TO FILE!"
fi
done
if [ "$number" -eq "$count" ]; then
echo " ALL FILE(S) IS UPPERCASED!"
else
echo " $count FILE(S) ALREADY UPPERCASED!"
fi
fi
# end of the "working part"!
--------------------------------------
但是，"declare -x filez=$(echo $i | /bin/awk BEGIN'{FS="/"} {print $NF}')" 一句中的 "declare" 在 cygwin 下的 sh 就认不出来了，我不知道其他版本的会不会有问题（我用的是 Red Hat 6.2）。其实，如果不行也可以把"declare -x " 换成 " && export filez " 就行了。
