我的.bashrc看起来像这样...
export PERL5LIB="/tools/perl/Linux/${PLAT}/lib/perl5/5.10.0/${PLAT}-thread-multi"
export PERL5LIB="${PERL5LIB}:/tools/perl/Linux/${PLAT}/lib/perl5/5.10.0"

我是linux的新手。我正在尝试将文件从一个路径复制到另一个路径。我有一个文本文件,其中包含以下模式的所有文件名:
file-1.txt
file-2.pdf
file-3.ppt
....
我用以下代码创建了一个.sh文件:
#!/bin/bash
file=`cat filenames.txt`;
fromPath='/root/Backup/upload/';
toPath='/root/Desktop/custom/upload/';
for i in $file;
do
filePath=$fromPath$i
#echo $filePath
我知道我可以用-z测试一个字符串是否为空,也可以用-n测试一个字符串是否为非空。所以我用ubuntu 10.10写了一个脚本:
#!/bin/bash
A=
test -z $A && echo "A is empty"
test -n $A && echo "A is non empty"
test $A && echo "A is non empty"
str=""
test -z $str && echo "str is empty"
tes
