I got some old shell scripts which use awk to replace some tags in a file called awkLog to make it more readable. The current command looks something like this:
awk log.txt -f awkLog > output.txt
The purpose is that the script is going to write data in log.txt like cpu usage and so on and after that it would "parse" the data and write it to output.txt in the order as specified in awkLog.
I looked for some replacements but unfortnaly I have no experience with shell scripting... I found that some are using the command cut. But I can't see how to implement this in the shell scripts.
The code of awkLog:
BEGIN maxfree = 0
minfree = 10000000000
savailable += $1
sused += $2
sfree += $3
sshared += $4
sbuff += $5
if ( $3 > maxfree ) maxfree = $3
if ( $3 < minfree ) minfree = $3
END print "MEMORY"
mavailable = savailable/NR
print "(average) available : ", mavailable
print "average used : ", sused/NR
print "average free : ", sfree/NR
print "average shared : ", sshared/NR
print "average buff : ", sbuff/NR
print "free max : ", maxfree
print "free min : ", minfree
print "Minimum MEMORY usage : ", mavailable-maxfree, "K"
print "Maximum MEMORY usage : ", mavailable-minfree, "K"
print "Average MEMORY usage : ", mavailable-sfree/NR, "K"
Inside the log.txt it looks like this:
User 1%, System 3%, IOW 0%, IRQ 0%
User 6 + Nice 0 + Sys 14 + Idle 420 + IOW 0 + IRQ 0 + SIRQ 0 = 440
PID PR CPU% S #THR VSS RSS PCY UID Name
10488 3 2% R 1 3704K 1248K fg shell top
Like I said I'm NO expert nor experienced user of shell scripting as I have ZERO experience with this so any help would be very much appreciated.
But it didn't work, maybe someone of you can help me?
Thanks in advance

awkis still very much supported (as in "it's not deprecated"). If you need to replaceawkwith something else, you would have to investigate what the current script (awkLog) is doing and re-implement that in some other language or using some other parser. You mentioned "tags", does this mean that the current script is modifying XML? Without seeing what theawkscript is doing, nobody can tell you what to replace it with.

Ok maybe to make things bit more clear I'm talking about the shell in an android phone. Maybe there it is no longer supported? Also the awkLog contains variables like $1, $2, ... and so on.

what I understood from your question is that you would like to replace a string in a file. if it so, sed is the better command.
sed -i 's/oldString/newString/g' log.txt

The word "tag" implies XML (possibly), in which case the proper "replacement forawk" would be a an XML parser.
