随机显示一条脚本技巧
从http://www.shell-fu.org/lister.php?random 会随机的显示一条脚本技巧. 把下面的内容放到bashrc中，运行shellfu即可，enjoy！ shellfu(){ curl -s "http://www.shell-fu.org/lister.php?random" | sed -e 's/ /\n<\/div>\n/g' | sed -n -e "/ /,/<\/div>/p" | lynx -stdin -dump -nolist; } 运行效果： 518 ~>shellfu The commmands below show the ten largest files/dirs in the working directory. Both commands give similar results, though handle things slightly differently. The 'du' option is good if you also need sizes of subdirectories, but the 'ls' option gives more detail. ls -laSh | head -10 du -s * | sort -nr | head -10 I find both to be useful in situations where I need to make more free space. 518 ~>shellfu Mail somebody about space running low in some path (ksh, bash): PATHS="/export/home /home" AWK=/usr/bin/awk DU="/usr/bin/du -ks" GREP=/usr/bin/grep DF="/usr/bin/df -k" TR=/usr/bin/tr SED=/usr/bin/sed CAT=/usr/bin/cat MAILFILE=/tmp/mailviews$$ MAILER=/bin/mailx mailto="[email protected]" for path in $PATHS do DISK_AVAIL=`$DF $path | $GREP -v "Filesystem" | $AWK '{print $5}'|$SED 's/%//g'` if [ $DISK_AVAIL -gt 90 ];then echo "Please clean up your stuff\n\n" > $MAILFILE $CAT $MAILFILE | $MAILER -s "Clean up stuff" $mailto fi done
