Shell Scripting
^ OVERVIEW
This local page for Bash shell scripts and notes on shell scripting.
^ Rename Badly Named Files
How to produce a usable filename which contains <ESC> characters, and to rename that badly named file:
$ ls -i 9704871 $'\033\033' 9703029 CMakeLists.txt 10899590 dts 9708845 samples $ ls -q `find . -inum 9704871` './'$'\033\033' $ mv './'$'\033\033' betterfilename
^ Git Diff-tree Helper Script
A helper script for calling `git diff-tree`, which can be used to determine at which project commit one or more files have changed:
#!/bin/bash
CMD_GIT=/usr/bin/git
$CMD_GIT log --oneline | head | cut -d " " -f 1
echo "2024-01-31 git diff-tree helper script in progress . . ."
hashes=`$CMD_GIT log --oneline | head | cut -d " " -f 1`
echo "In $PWD found git commit hashes:"
echo " " $hashes
#i=1
#for hash in $hashes; do echo "("$i")" $hash; (( i++ )); done
#echo "Files changed between commit pairs youngest pairings to oldest:
for hash in $hashes; do echo "Files changed in git commit:"; git diff-tree -r $hash; echo; done
echo "done"
exit 0
