貓の中秋’s blog~

星期二下午得闲, 只猫话想去影贴纸相, 甘我更系立即应承啦.
林翻起第一次同佢影贴纸相… 果时真系失败啊…
点知今次都5好得去边. 我个面实在5系影相的料, 乜表情都好似好猥琐甘, 唯有乜表情都5做啦.
只猫就更系点影都甘可爱啦~… ^_^~．．

后来又去佐革新路买嘢… 因为赶时间搞到生死时速甘啊.
高考前可能很少有机会同佢一起行街街啦~.. missing you!!

Mailing Lists 狂退信, 以为是墙拦住了.
后来发现原来是 Tom 邮箱限制邮件数为 1000, 一脚TF.
换成 sina 啦..

昨天猫猫18岁生日啦！！！好开心啊。佢地屋屋仲要成家人来齐晒（巧合）。。算5算一起贺佢呢？
我送佐只杯比佢，好似好5等使甘tim。
原先我想稳只猫形的杯咖，好似韵怡只鸡杯甘的。。点知稳5到，真系可惜啦。

希望只猫可以考上理想大学啦!!!　猫猫加油，我爱你～

RT, 发现多个 session 时可以自己选择

if (system("which screen > /dev/null") == 0) {

        exec "$screen_command" , @ARGV ;

screen 包装脚本, 根据具体情况决定 screen 的启动方式.
Multi display mode 很好玩的说.

#!/bin/sh
# A wrapper for screen,

RUN_DIR='/var/run/screen/S-bigsnake-net'
SCREEN_COMMAND=`which screen`

if ! which screen >/dev/null ; then echo "screen not found" ; exit 1; fi

if [ $# -gt 0 ] ; then
    exec $SCREEN_COMMAND "$@"
else
    if [ -d $RUN_DIR ] ; then
        case `ls $RUN_DIR|wc -l` in
            0)
            exec $SCREEN_COMMAND
            ;;
            1)
            exec $SCREEN_COMMAND -x
            ;;
            *)
            exec $SCREEN_COMMAND -R
            ;;
        esac
    else
        exec $SCREEN_COMMAND
    fi
fi

在 X 终端启动 GUI 程序的小脚本, 其实压住输出和使之后台运行

#!/bin/sh

if  [ $# -gt 0 ] && which $1 > /dev/null ; then
    exec $@ 1>/dev/null 2>/dev/null &
else
    echo -e "gui - A GUI program wrapper.\nUsage: gui COMMAND [OPTION]..."
fi
