刪除 core 文件
# find ~ -name core -exec file {} \; -exec rm -i {} \;
查看使用文件的進程
# fuser -u /usr/my_application/foo
搜索字符串
#grep "hello world" `find ./ -name "*" -print -exec file {} \; grep text cut -d ':' -f 1`
目錄
#alias dir='ls -Llagrep ^d'
輸出 IP 地址
#ifconfig grep "inet addr" grep -v "127.0.0.1" awk '{print $2;}' awk -F':' '{print $2;}'
按文件長度排序
#ls -l grep ^- sort -nr -k 5 more
#ls -lR grep ^- sort -nr -k 5 more
二進制文件中的可打印字符
# strings name of binary file
一個月的最後一個星期天執行任務:
18 * * * 0 [`date "+%d"` -gt 24] && /path/to/script
修改擴展名:
# for f in *.abc; do mv $f `basename $f .abc`.def ; done
查看硬盤情況:(Solaris)
# iostat -En
整個目錄樹拷貝:
# cd
# find . -depth -print cpio -pudm
按長度排序目錄下所有文件
# du -a sort -n -r more
檢查文件內每行是否有相同列數
#awk '{print NF}' test.txt sort -numore
去除空行
#sed -e '/^[ ]*$/d' InputFile >OutputFile
查看進程占用的對應文件 inode 號(Solaris)
#/usr/proc/bin/pfiles
刪除指定用戶的所有進程
# kill -9 `ps -fu username awk '{ print $2 }'grep -v PID`
Bash 操作快捷鍵:
ctrl-l ―― clear screen
ctrl-r ―― does a search in the previously given commands so that you don't
have to repeat long command.
ctrl-u ―― clears the typing before the hotkey.
ctrl-a ―― takes you to the begining of the command you are currently typing.
ctrl-e ―― takes you to the end of the command you are currently typing in.
esc-b ―― takes you back by one Word while typing a command.
ctrl-c ―― kills the current command or process.
ctrl-d ―― kills the shell.
ctrl-h ―― deletes one letter at a time from the command you are typing in.
ctrl-z ―― puts the currently running process in background, the process
can be brought back to run state by using fg command.
esc-p ―― like ctrl-r lets you search through the previously given commands.
esc-. ―― gives the last command you typed.
文件名裡的空格替換為下劃線
# for i in $1 ; do mv "$i" `echo $i sed 's/ /_/g'` ; done
查看遠程主機時間
# telnet remotehostname 13grep :
只顯示 top 命令的states 行
#while true; do top -d 2 col -b grep states; sleep 10; done
加速顯示 tar 文件內容
# tar tvfn
讓 目錄名也能 Spell Check
#shopt -s cdspell
當輸錯命令時,系統會自動進入類似的目錄

# /usr/platform/`uname -m`/sbin/prtdiag -v grep `uname -m`
在vi 中一行文字前後添加字符
:/^\(。*\)/s//我要 \1 添加/
查找某包含字符串(Verita)軟件包的詳細信息 (Solaris)
pkginfo -l `pkginfo grep -i VERITAS awk '{print $2}'`
