Today, I learned a little bit about the shell programming under Linux and simply recorded the test cases.1. Edit the shell script file as follows:#!/bin/bashecho "Hello Bash Linux"echo "No. 0 parameter: $ A"echo "First parameter: $ $"echo "Current child shell process: $$"#pidarr = ' PS x | awk ' {print '} 'pidarr=$ (ps x | awk ' {print $} ')Echo $pidaddFor ID in $pidarrDoecho "$id"Done2. Save As file Test.b
There is a batch of IDs in the HTML, ending with numbers + fixed characters, and the foreground needs to pass this batch of IDs into the backgroundSuppose that the fixed trailing character is "pic", using var pidlist=$ ("[id$= ' pic ']"), and all the matching HTML is removedThen remove the ID:for (Var i=0;iAlert (pidlist[i].id.substring (0,pidlist[i].id.length-3));}3 is to remove the existing "pic", get the
