sed find line and replace a spacific character in the last 7 characters



I would like to replace a space character in the last seven characters of a line
that starts with the following pattern: "start-string"


"start-string"



Example of the file content :


randomdata 33243as4a4S3342as3A4S3A3s13aw38q363s4 sd7asd312vff74 41g5rfg45f5d3q

start-string 4d d5f5d4fd4f5g6r fgdf dhfhdgnmasj 32121fdfdf21g 45s6g76t2 20



I need to replace the last space character of the line that starts with "start-string" and leave the other line as it is with no edit in the file.


"start-string"



Another question - how can I combine more than one regex command in sed?

Makefile test if variable is not empty

Makefile test if variable is not empty In a makefile I'm trying to I've created this simplified makefile to demonstrate my problem. Neither make a or make b executes the body of the if, I don't understand why not. make a make b .PHONY: a b a: $(eval MY_VAR = $(shell echo whatever)) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should be executed" endif @echo done b: $(eval MY_VAR = $(shell echo '')) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should not be executed" endif @echo done I'm using $ make --version GNU Make 3.81 There are several problems, and misunderstandings. Your MY_VAR is a make variable, set it without a <tab> to its value, and no need to $(eval ...) . MY_VAR:=$(shell echo whatever) is enough. No <tab> before $(info ...) neither, this is make – Zelnes ...
