git stash saver! #vcs

backup stashes to files

#!/bin/bash

# This may not be the best -or even a good- practice! but it works well for my requirements, and that has no guarantees it should work well in all cases
# Stashes are OVERWRITTEN, so if u had anything named stash[0-9]+.diff it will be OVERWRITTEN, this was an intended behavior for my case, no checks are provided :-|
# No Warranties at all, just have your backups available ^_^
# This code is more focused on trying different shell scripting operations

git stash list > ./stash_list_temp

# to assign use equal directly after the variable name
# to get the RHS assigned from a script use $(script) and ensure no spaces between the = and the $
ST_NO=$(wc -l stash_list_temp | tr -cd 0-9)

# Variable printing
echo $ST_NO

echo "number of stashes is $ST_NO"

# Assign a new value to the variable
# Works with #!/bin/bash but not with #!/bin/sh
let "ST_NO -= 1"

## Do arith operations on variables
#echo "number of stashes is $(ST_NO + 1)"

# For loop
for i in $(seq 0 $ST_NO)
do 
  #that could be optimized to name the scripts directly to the stashes!
  #but this is another version :D
  STASHNAME="stash$i.diff"
  git stash show -p stash@{"$i"} > $STASHNAME
  echo "stashed into $STASHNAME"
done

## Sequence Creation
#a=$(seq 1 4)
#echo $a

#TODO sanity checks (ie: stashes are available or not!)
