It's tested on CentOS 7. Before use it, you must install zip and ImageMagick: yum install zip ImageMagick and unrar: # wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm # rpm -Uvh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm # yum update # yum install unrar Create a exectable file (it names "rarresizer.sh" here.) with Code below: #!/bin/bash mkdir ./tmp mkdir ./produced IFS=$'\n' for UNRARFILE in $( ls *.rar ); do echo item: $UNRARFILE UNRARCACHE="${UNRARFILE%.rar}" mkdir ./tmp/$UNRARCACHE unrar x $UNRARFILE tmp/$UNRARCACHE find ./tmp/$UNRARCACHE -name *.jpg -print -exec mogrify -resize x1308\> {} \; find ./tmp/$UNRARCACHE -name *.png -print -exec mogrify -resize x1308\> {} \; find . -name *.txt -exec rm -f {} \; find . -name *.url -exec rm -f {} \; cd ./tmp zip -0 -r ../produced/$UNRARCACHE.zip ./$UNRARCACHE cd .. done echo done\! unset IFS You can change resize parameter with width x...

It's tested on CentOS 7. Before use it, you must install zip, unzip and ImageMagick: yum install zip unzip ImageMagick Create a exectable file (it names "zipresizer.sh" here.) with Code below: #!/bin/bash IFS=$'\n' mkdir ./tmp mkdir ./produced for UNZIPFILE in $( ls *.zip ); do  echo item: $UNZIPFILE  UNZIPCACHE="${UNZIPFILE%.zip}"  mkdir ./tmp/$UNZIPCACHE  unzip $UNZIPFILE -d tmp/$UNZIPCACHE  find ./tmp/$UNZIPCACHE -name *.jpg -print -exec mogrify -resize x1308\> {} \;  find ./tmp/$UNZIPCACHE -name *.png -print -exec mogrify -resize x1308\> {} \;  find . -name *.txt -exec rm -f {} \;  find . -name *.url -exec rm -f {} \;  cd ./tmp  zip -0 -r ../produced/$UNZIPFILE ./$UNZIPCACHE  cd .. done echo done\! unset IFS You can change resize parameter with width x height like this: find ./tmp/$UNZIPCACHE -name *.jpg -print -exec mogrify -resize 512x1308 {} \; or by percentage: find ./tmp/$UNZIPCACHE -name *.jpg -print ...

延伸Vol_Group的空間 先於VMware延伸vmdk的大小之後，Power On。 進入CentOS後： 利用fdisk將先前所延伸出來的空間做成ext4 Linux LVM (8e) pvcreate /dev/sda3 pvscan pvdisplay vgextend VGNAME /dev/sda3 ，記錄Free PE的數值 lvdisplay，記錄需要擴充的Logical Volume lvresize -l +3918 /dev/VolGroup/lv_root lvdisplay df -h，此時已經擴充完畢，接上來要通知FileSystem resize2fs /dev/VolGroup/lv_root df -h

NIC eth0 is gone Solution: 刪除/etc/udev/rules.d/70-persistent-net.rules後重新開機 # cd /etc/udev/rules.d # cp 70-persistent-net.rules /root/ # rm 70-persistent-net.rules # reboot Configure NIC onboot Update your /etc/sysconfig/networking-scripts/ifcfg-eth0 with eth1 HWaddr (MAC address), enter: # cat /etc/sysconfig/networking-scripts/ifcfg-eth0 Sample outputs: # DEVICE="eth0" # BOOTPROTO="dhcp" # NM_CONTROLLED="yes" # ONBOOT="yes" # HWADDR="00:0C:29:69:0C:4A" Save and close the file. Restart the network service, enter: # service network restart You can verify new settings with the following commands: # ifconfig -a # route -n Change keyboard layout Change keyboard layout to English keyboard # loadkeys us Change default keyboard layout to English keyboard # vi /etc/sysconfig/keyboard // need root permission // vi text editor # KEYTABLE="us" # KEYBOARDTYPE="pc" // type "ESC...
