How to use bash regex inside Makefile Target

由 对着背影说爱祢 提交于 2021-02-09 17:42:55
问题 In a bash script, the following regex appears to work well: MY_STRING="FirstName-LastName-Gender-Age" MY_REGEX="([^-]+)-([^-]+)$" if [[ $MY_STRING =~ $MY_REGEX ]]; then echo "Match: $BASH_REMATCH" fi I'm interested in using this script inside the Makefile. It appears to have syntax issues. For example: my-target: MY_STRING="FirstName-LastName-Gender-Age" MY_REGEX="([^-]+)-([^-]+)$" if [[ $MY_STRING =~ $MY_REGEX ]]; then echo "Match: $BASH_REMATCH" fi What would be the correct syntax for this

Delete pattern from a variable with sed

由 折月煮酒 提交于 2021-02-09 12:28:13
问题 I am working with a script that has a variable called PRODUCT_VERSION . The version comes with a dot (for example 6.0 ). I need to remove the dot and save the result in another variable. So far I come with this, but it does not work correctly PRD_VER=$(sed "s/$PRODUCT_VERSION/\.//g") 回答1: $ PRODUCT_VERSION=6.0 $ PRD_VER=${PRODUCT_VERSION/.} $ echo $PRD_VER 60 Bash String Manipulation Examples 回答2: This might work for you (GNU sed & bash): NEW=$(sed 's/\.//g' <<<"$OLD") or NEW=$(echo "$OLD" |

The way to detect the current mouse cursor type from bash or python

由 走远了吗. 提交于 2021-02-09 08:20:47
问题 I know that I can get the current location of the mouse cursor by executing "xdotool getmouselocation". I would like to detect the current mouse cursor type such as pointer, beam, or hand cursor from bash terminal or python code. Would this be possible? Thank you. June 回答1: You can use xdotool to continuously click where the link would be until the program notices the window title changes. When the window title changes, that means the link has been clicked, and the new page is loading.
